[0002] The present invention relates to methods and compositions for synthesizing 5'-capped RNA. In an embodiment, the present invention provides a method for the preparation of natural or modified 5'-cap 0, cap 1, cap A novel capping agent with trimethylguanosine-cap (TMG-cap) structure In a further aspect, the present invention relates to a 5-stranded initiation oligonucleotide primer. The present invention relates to a method for efficiently producing 5'-capped RNA and using the same. Methods for preparing the labeled RNA are provided. [Background technology]

[0003] The following explanation is provided to aid the reader's understanding. None of the references are admitted to be prior art in this invention.

[0004] Messenger RNAs that code for proteins of physiological importance for therapeutic applications ( mRNA) is a DNA-based plasmid and viral vector for delivering genetic material. The most important of these advantages are: be: (i) High level of safety (no chance of genome damage from viral or plasmid integration) (reduce (ii) mRNA delivery results in immediate protein expression (when using plasmids) (different from the delayed response that typically occurs in (iii) mRNA allows for robust, dose-dependent control over protein expression , and (iv) Large-scale synthesis of mRNA compared to plasmid and viral vector production. Simplicity.

[0005] The messenger RNA can code for virtually any known protein, Delivery to specific tissues and organs can be achieved by a variety of methods known to those skilled in the art. Once delivered, these mRNAs are used to express ribosomal proteins in targeted tissues. It directs the expression of various proteins, resulting in the production of hundreds of proteins per mRNA molecule.

[0006] present in each active mRNA molecule for efficient translation of the encoded protein Several structural elements are utilized to facilitate the synthesis of mRNA. A cap structure on the 5' end of A, which is found in all eukaryotes (and some The naturally occurring cap structure is a methyl group at the N7 position of the guanine base. This 7-methylguanosine ( 7m G) is mR The NA molecule is linked via a 5'-to-5'-triphosphate chain at the 5' end. , 7m and m7 are used synonymously and have the same meaning. 7m Gpp The presence of the p fragment is essential for mRNA maturation. Protects mRNA from exonucleolytic degradation Promotes transport of mRNA from the nucleus to the cytoplasm, It plays an important role in the assembly of the translation initiation complex (Cell 9:645-6 53, (1976); Nature vol. 266:235, (1977); Fede ration of Experimental Biologists Societ y Letters 96:1-11 (1978); Cell 40:223-2 4, (1985); Prog. Nuc. Acid Res. 35:173-20 7, (1988);Ann.Rev.Biochem.Volume 68:913~963 , (1999); J. Biol. Chem. Vol. 274: 30337-3040 (1 999)).

[0007] In cap-dependent translation, only mRNAs that retain the cap structure are active; "Decap" of mRNA terminates almost completely its template activity for protein synthesis. (Nature, vol. 255:33-37, (1975); J. Bi ol. Chem., vol. 253: 5228-5231, (1978); and Proc. c. Natl. Acad. Sci. USA, vol. 72: 1189-1193, (197 5 years)).

[0008] Another element in eukaryotic mRNAs is the presence of several In the case of The presence of 2'-O-methyl groups in mRNA is a key factor in the in vivo translation of mRNA. This is necessary for higher efficacy (Proc. Natl. Acad. Sci. USA, 77:3952-3956 (1980)), nuclease of 5' capped mRNA mRNA with cap 1 (and cap 2) further improves enzyme stability. This allows the cytoplasmic repressor to recognize the authentic 5' end of the mRNA and, in some cases, to recognize the infectious gene. Nucleic Acid Receptor arch 43:482-492 (2015).

[0009] Primary mRNA transcripts are RNA sequences that are initiated in vivo with NTPs (usually GTP). It retains the 5'-triphosphate group (5'-pppmRNA) that results from the initiation of mRNA transcription. The conversion of the 5'-triphosphorylated end of a transcript to a cap structure (Cap 0) is achieved by several enzymes. (J. Biol. Chem. 250:9322 (1975) 271:11936 (1996);J.Bio Chem. 267:16430 (1992). These enzymatic reaction steps The following groups are available: Step 1: RNA triphosphate enzyme converts the 5'-triphosphate of mRNA to 5'-diphosphate Convert to pppN1(pN) x →ppN1(pN) x + inorganic phosphate, Step 2: RNA guanyltransferase uses GTP to attach a GMP residue Transfer to the 5'-diphosphate of mRNA, ppN1 (pN) x +GTP→G(5')ppp(5 ')N1(pN) x + inorganic pyrophosphate, and Step 3: Guanine-7-methyltransferase reacts with S-adenosine as a cofactor. AdoMet is used to convert AdoMet to the 7-nitrogen of the guanine base. Transferring a methyl group, G(5')ppp(5')N1(pN) x +AdoMet→ 7m G(5 ')ppp(5')N1(pN) x +AdoHyc). The RNA resulting from these enzymatic activities is called "5'-capped RNA" or "capped RNA". The enzymes involved in this process, which result in the formation of "capped RNA," are called "capped RNAs." The combination of enzymes is called a "capping enzyme." Capping enzymes, including cleaved forms, have been identified and purified from a number of sources. and are well known in the art (Prog. Nucleic Acid Res. ol.Biol.Vol.66:1~40, (2001);Prog.Nucleic Acid Res. Mol. Biol. 50:101-129, (1995); and Microbiol. Rev. 44:175, (1980). Capsids are formed by the addition of cap nucleotides to the 5' end of primary RNA by a capping enzyme. The capped RNA is called a capped RNA with a "Cap 0 structure" (JB iol. Chem. 269:14974-14981, (1994); J. Biol. Vol. Chem. 271: 11936-11944 (1996). Cap type The enzyme is used to synthesize capped RNA with a cap 0 structure in vitro. (J. Biol. Chem. vol. 255: 11588, (1980 ); Proc. Natl. Acad. Sci. USA Vol. 94: 9573, (1997 267:16430, (1992);J.Bi ol. Chem. 269:14974, (1994); and J. Biol. hem. vol. 271:11936, (1996)).

[0010] Capped RNA with a 5'-Cap 0 structure is a (nucleoside-2'-O-) methyl This is further converted in vivo to the “cap 1” structure by the action of methyltransferase. (J. Biol. Chem. vol. 269: 14974-14981, (19 1994); J. Biol. Chem. Vol. 271: pp. 11936-11944, (199 6; and EMBO 21:2757-2768, (2002). For example, Vaccinia mRNA (nucleoside-2'-O) methyltransferase is a nucleotide analogue of The reaction results in the penultimate nucleotide of the 5' end of the 5' capped RNA with a Cap 0 structure. Can catalyze the methylation of the 2'-hydroxyl group of nucleotides: 7m G(5')ppp(5')N1pN2(pN) x +AdoMet→ 7m G(5') ppp(5')N1 2’-OMe pN2(pN) x +AdoHyc.

[0011] Dimethylated capped RNA with a cap 1 structure is more efficient than capped RNA with a cap 0 structure. It has been reported that RNA is translated more efficiently than RNA with a nucleic acid sequence similar to that of the nucleic acid sequence ... Res. 26:3208 (1998). Eukaryotic cells use another -2'-O) methyltransferase (e.g., hMTR2(Nuclease) in human cells) Acids Res. 39:4756 (2011)) The reaction results in the 2'-hydroxylation of the second transcribed nucleotide of the 5'-capped RNA. Catalyzes the methylation of the silyl group to convert the cap 1 structure to the cap 2 structure: 7m G(5')ppp(5')N1 2’-OMe pN2(pN) x +AdoMet→ 7 m G(5')ppp(5')N1 2’-OMe pN2 2’-OMe (pN) x +AdoH yc. Approximately 50% of eukaryotic mRNAs contain the Cap2 structure.

[0012] In the mid-1980s, in order to generate long functional RNA for various biological studies, In 2011, a method for the in vitro enzymatic synthesis of primary RNA was developed (Methods Enzymatic Synthesis). zymol. Vol. 180: pp. 51-62, (1989); Nucl. Acids Re s., vol. 10: 6353-6362, (1982); Meth. Enzymol. , Vol. 180: pp. 42-50 (1989); Nucl. Acids Res., No. 12 Volume: 7035-7056, (1984) and Nucleic Acid Research arch 15:8783-8798, (1987).

[0013] After in vitro transcription, the primary mRNA transcripts retaining the 5'-triphosphate group were capped However, in vitro enzymatic capping is not possible. 5'-capping is expensive, laborious, inefficient and difficult to control. It is difficult to do so.

[0014] Considering these disadvantages, chemically synthesized dinucleotides 7m G(5')ppp of capped mRNA, which initiates transcription using (5')G (also called mCAP) An alternative method for in vitro synthesis has been developed (RNA 1:957-967 , (1995)). The mCAP dinucleotide is the 5'-cap structure of mature mRNA. contains 2'-O-methyl nucleosides characteristic of the cap 1 and cap 2 structures. It does not have a

[0015] However, due to the initiation of in vitro transcription using synthetic mCAP dinucleotide There are two main disadvantages to using ppp-peptide synthesis. pppG is a strong competitor for pppG. When pppG is used to initiate mRNA, the resulting p-mRNA is translationally and immunogenically inactive due to the presence of 5'-triphosphate. Correspondingly, when mRNA is primed with mCAP, the resulting 5' cap The attached mRNA is translationally active but immunogenically inactive.

[0016] 5'-capped or 5'-uncapped (or 5'-triphosphorylated; pppm To improve the proportion of 5'-capped mRNA transcripts (up to 8 0-90%), the excess over pppG 7m GpppG(4 A downside to this approach is that transcription Rapid depletion of GTP supplies and the need for large amounts of synthetic mCAP dimers, which can be expensive This results in a significant reduction in the overall yield of mRNA. The crude mixture containing both A and 5'ppmRNA was purified with alkaline phosphatase. Further processing can be used to convert pppmRNA to cis-peptides to reduce the immunogenicity of the synthesized mRNA. This is necessary to remove the uncapped 5'-triphosphate group. The uncapped 5'-OH form of the mRNA is inactive and does not participate in the translation process. do not have.

[0017] Another disadvantage occurs when using asymmetric mCAP dinucleotides: bidirectional initiation. It is possible. 7m G in GpppG or 7m of any 3'-hydroxyl group of the G moiety, They tend to serve as initiation sites for transcription elongation with roughly equal probability. Depending on the type, approximately equal proportions 7m G(5')pppG(pN) n and G(5 ')ppp 7m G(pN) n This leads to the synthesis of two isomeric RNAs (RNA Vol. 1:9 pp. 57-967, (1995)).

[0018] To eliminate bidirectional initiation of mRNA synthesis when using mCAP dinucleotide , 7m A novel modified mCAP analogue in which the 3'-OH group of the G residue was replaced by OCH3 ("OM e"): 7m G(3'-O-Me)pppG (Anti-reverse cap analog) -Reverse Cap Analog (ARCA) was developed. ARCA initiates mRNA synthesis only in the correct forward orientation (RNA vol. 7: Several types of ARCA analogs are known in the art. (See, for example, U.S. Patent No. 7,074,596). To ensure that most mRNA transcripts have a 5'-cap structure, ppp A large molar excess of ARCA over G is still required. 1 structure of mRNA is 7m GpppG 2’-OMe Cap dimer (RNA vol. 1 957, (1995)) or its ARCA analogues. That is the thing.

[0019] Currently, the only known pathway for the generation of active long mRNAs containing the Cap1 structure is the enzyme Enzymatic 2'O-methylation of elementary capping and 5'-triphosphorylated mRNA transcripts is the enzymatic 2'-O-methylation of mCAP- or ARCA-capped pre-mRNA. Nucleosides, Nucleotides, and Nucleic A cids, vol. 25: 337-340, (2006) and Nucleosides ,Nucleotides,and Nucleic Acids Vol. 25(No. 3):3 Both approaches are quite labor intensive. are difficult to control, and even with substantial optimization, both approaches However, it is not possible to guarantee a high yield of capped and methylated pre-mRNA (J. Gen. Virol., 91:112-121, (2010). Furthermore, the cap 2 structure The methods for preparing mRNA with the desired structure are much more difficult and the results are less predictable. The enzyme for converting cap 1 to cap 2 is not currently commercially available.

[0020] Another important complication of in vitro synthesis of mRNA, especially for large-scale production, is the inactivation All uncapped mRNA forms are virulent and, in some cases, immunogenic. Therefore, it is necessary to isolate and purify active mRNA molecules that retain the cap. Unfortunately, these methods are not trivial and require extensive purification of capped RNA transcripts. Modified IgG antibodies conjugated with an affinity tag moiety that allows for easier isolation and purification. Synthesis of mCAP analogs with affinity as a reporter / affinity moiety is often required. Methods for synthesizing tagged mCAP analogs and isolating capped RNA from transcription reaction mixtures Novel protocols for the isolation of A are known in the art (e.g., U.S. Pat. No. 8,333,636). (See, e.g., 344,118.) Although these approaches are effective, they This requires the use of many more expensive mCAP analogs, and mRNAs containing only the Cap0 structure are This allows for the preparation and isolation of A.

[0021] In vitro synthesis of natural and modified RNA has been used to create ribozymes, antisense and biological It is used in a variety of applications, including physical and biochemical research. RNA transcripts were used in in vivo expression experiments (microinjection, transfection, etc.) tion and infection), in vitro translation experiments and assays, and treatments Various applications in drug, diagnostic, and vaccine development, labeling and detection abo-thib protein synthesis It is used for applications requiring

[0022] As a result, (a) it is less labor intensive than traditional methods, and (b) there is no need for double transcription. (c) eliminate or reduce directional initiation; (d) at a reduced cost compared to current methods; (e) generation of heterogeneous products with different 5' sequences, resulting in higher yields of RNA; (f) to incorporate cap 1 and cap 2 structures into the synthesized mRNA; Compositions and methods for large-scale synthesis of mRNA without the need for additional enzymatic reactions There is a need in the art for methods to provide specific modifications and modifications at or near the 5' end of the molecule. and / or affinity tags, such as fluorescent dyes, radioisotopes, mass tags, and / or biotin Modified and / or non-natural nucleic acids that retain one partner of a molecular binding pair, such as a nucleic acid The synthesis of various mRNAs containing nucleotides is also required.

[0094] Transcription In eukaryotes, transcription of messenger RNA (mRNA) is initiated by RNA polymerase II. This is a complex multi-subunit enzyme with intricate regulation. To perform large-scale transcription in vitro, researchers generally use T7, T3, SP 6, single subunits derived from K1-5, K1E, K1F or K11 bacteriophages This family of polymerases uses accessory phage polymerases. It does not require a protein and has minimal constraints on the starting nucleotide sequence, approximately 17 nucleotides. The present application relates to a simple minimal promoter sequence for T7 RNA polymerase (T7 Although the present invention focuses on RNA polymerase P), those skilled in the art will appreciate that the present invention can be applied to other RNA polymerase Ps. It will be appreciated that the present invention may also be practiced using a laser.

[0095] T7 RNAP exists in at least two protein states. The first is the "A The second, called the "abortive complex," is involved in transcription initiation. This conformation is called the "elongation complex" and is highly processive. can be divided into six steps: 1) RNA polymerase promoter sequence 2) initiation of transcription; and 3) abortive transcription, during which the polymerase 4) non-processive elongation, which frequently releases the DNA template and short abortive transcripts, and 4) the open complex 5) processive elongation and 6) transcription termination. A significant amount of RNA consists of short abortive fragments of approximately 2–8 nucleotides in length (Bioc hemistry vol. 19: 3245-3253 (1980); Nucleic A cids Res. Volume 9: 31-45 (1981); Nucleic Acids Res. 15:8783-8798 (1987); Biochemistry 27:3966-3974 (1988). After synthesis of about 10-14 bases, RNA The polymerase escapes from abortive cycling and simultaneously aligns with the promoter DNA. They lose sequence-specific contacts and form a processive elongation complex, in which the RNA strand advances in a sequence-independent manner. (J. Mol. Biol. vol. 183: 165-177 (1985); P roc. Natl. Acad. Sci. USA Vol. 83: 3614-3618 ( 1986); Mol. Cell Biol. Vol. 7: pp. 3371-3379 (1987) year)).

[0096] The consensus sequence for the most active class III T7 promoters is It includes 17 bp of upstream sequence and 6 bp downstream (Cell 16: 815-25 (1979)). The position of the first transcribed nucleotide is generally the +1 transcript of the RNA. The second transcribed nucleotide is called the +2 transcribed nucleotide. During transcription, the two strands melt together, forming a transcription bubble, which separates the double-stranded The bottom strand (designated 3' to 5' in Table 2) is the template for transcription. For nucleotides +3 and above, the template strand is primarily Watson-Crick Base pairing interactions define the identity of the transcribed nucleotide. The nucleotide that codes for the RNA transcript nucleotide is defined as the +1 nucleotide of the template. In the example shown in Table 2, the +1 transcript nucleotide is G and the +1 template nucleotide is G. Similarly, the +4 transcript nucleotide is A and the +4 template nucleotide is C. The punch line is T.

[0097] [Table 2]

[0098] Unlike DNA polymerases, T7 RNAP synthesizes RNA in the absence of a primer. The first step in initiation is called de novo RNA synthesis, In this case, RNA polymerase recognizes a specific sequence on the DNA template and binds to positions +1 and + a first pair of nucleotide triphosphates that are complementary to the template residues of 2 and a dinucleotide triphosphate that is complementary to the template residues of 2; The initiating nucleotide is reacted with the polymerase The Kd value is calculated based on the first starting N The Kd for the first TP is 2 mM and for the second it is 80 μM, whereas the Kd for the second TP is 2 mM and for the third TP it is 80 μM. The actual NTP concentration is approximately 5 μM (J. Mol. Biol. (2007) Vol. 3, No. 1). 70, pp. 256-268). De novo synthesis is the rate-limiting step in transcription. It has been shown that T7 RNAP has a high affinity for GTP as the initiating nucleotide. (J. Biol. Chem. 248:2235-2244 (1999) Of the 17 T7 promoters in the genome, 15 are GTP-terminated (and 13 are pp pGpG) whereas there is no apparent NTP preference during transcription elongation (J. Mo Biol. 370:256-268 (2007). T7 RNA polymerase The enzyme initiates poorly on promoters that code for an A at position +1 and instead Transcription primarily initiates at the coded G at position +2 (J. Biol. Chem. vol. 278). Vol.:2819-2823 (2003).

[0099] During de novo RNA synthesis, the binding of the initiating nucleotide occurs via base stacking. , the specific interactions between the polymerase residues, the guanine portion of the initiating nucleotide, and the base This is mainly achieved by the free energy generated by complementary interactions (J. Mol. B iol. 370:256-268 (2007)).

[0100] T7 RNAP can also be initiated using short oligonucleotide primers. For example, 13 promoters in the T7 genome are expressed using pppGpG. It has been found that the β-amyloid ... Several groups have demonstrated that T7 RNAP binds dinucleotide primers (Biochemistry Vol. 24: 5716-5723) Axelrod et al. (1985) reported that the uncapped GpA dinucleotide The +1 and +2 constructs are 2'-deoxycytidine and 2'-deoxythymidine, respectively. They showed that it is possible to start with a 20-nucleotide template (the "CT" template). 0 micromolar (μM) dimer and 100 μM ATP, CTP, GTP and U Their reaction mixture also contained 100 μM 3' dATP, 3' dCTP They contained 50 μM 3' dUTP or 50 μM 3' dGTP. We observed only RNAs primed with a mixture of GpA and 5′-GTP primed RNAs. 'We did not observe any triphosphate RNA. This may be due to the reaction conditions used. 100 μM GTP inhibits the 2′ reaction of T7 polymerase to the first initiating guanosine. This is significantly lower than the mM Kd (J. Mol. Biol. (2007) Vol. 370, 25 (pp. 6-268). GTP competes for initiation with the initiator oligonucleotide. Using low GTP concentrations favors GpA initiation but results in low transcription yields. (maximum calculated yield estimated to be <150 μg / mL reaction). When transcription is initiated on a "CT" template using CpG, UpG, or GpG, they The 5′ nucleotide sequence is a transcription factor that mediates the formation of RNA transcripts and further untemplated 5′ nucleotides. The three observed morphologies were A, C, U, or G, respectively.

[0101] Axelrod et al. also used an uncapped GpG dinucleotide to The primers +1 and +2 are 2'-deoxycytidine ("CC" template) promoter. They observed low fidelity of initiation and produced three distinct transcripts. They observed that "examination of the autoradiographs shows that one member of each triplet Due to the initiation of a GpG at the normal (+1) position, the second member of each triplet is The third member of each triplet is the normal GpG at position (-1). This indicates that the GpG gene is due to the initiation of the guanosine triphosphate at position φ1. 0 promoter ("CC" template) and φ1.1A promoter ("CT" template) were used. If so, it is a relatively weak initiator and does not react with guanosine triphosphate at the concentration used. "The φ10 promoter is a key regulator of transcription and regulation of transcription in normal cells," they said. No initiation with the GpA dinucleotide was observed using the "CC" template. , ApC and ApA are initiators with either the above "TC" or "CC" templates. These did not act as targets for the template nucleic acid at positions +1 and +2, presumably because they This is because the method described by Axelrod et al. , which was designed for the generation of extremely small amounts of radioactive transcripts for sequencing. and is not suitable for large-scale production of useful pharmaceutical amounts of RNA. To increase the yield of RNA, NTPs containing an initiating dimer of 1000 and GTP are used. The expected result is that GTP reacts with the +1 nucleotide at an NTP concentration close to its Kd (2 mM). Since it competes effectively with the dimer for initiation of RNA, with a large proportion of RNA being generated starting with pppG.

[0102] Pitulle et al. showed that transcription using T7 RNAP results in the synthesis of uncapped oligonucleotides. We have shown that the ribozyme can be initiated using 2-mer to 6-mer ribozymes (Gene, Vol. 112:1 01-105 (1992). These oligonucleotides have a 5'-OH or 5 They also contained oligonucleotides of the structure biotin-ApG. All of the oligonucleotides used in this study were , which contained a 3'-terminal G. Pitulle et al. also Generates RNA transcripts with 2'-O-methylated or 2'-deoxy residues near the termini To achieve this, it is advisable to include 2'-O-methyl and deoxy residues in the primer sequence. In this publication, we have demonstrated that it is possible to ligate the 3' end of any starting oligonucleotide. It is clear that the anosine residue is paired with the +1 template nucleotide. This results in non-templated nucleotides being added to the 5' end of the RNA. The authors write, "Apart from the Y-terminal G, base pairing with the template DNA is not required, so this sequence "Sequence variations in the starting oligonucleotide fragment are easily possible." The nucleotide primer is perfectly compatible only with the template nucleotide "C" at position +1. is complementary to any nucleotide at subsequent positions (+2, +3, etc.) This is confirmed in a subsequent methodological paper by this group (M ethos Mol Biol. 74:99-110 (1997), Meth ods Mol. Biol. vol. 252: 9-17, (2004). indicates that all nucleotides of the initiating capped oligonucleotide primer are at position +1 and a nucleotide sequence as described herein that is completely complementary to the template nucleotide at the subsequent position. The method is different. Kleineidam et al. 5'-modified tRNA transcripts were generated by initiation with dimers or trimers modified with (Nucleic Acids Research, Vol. 21, pp. 1097-1101) 1993). Again, the authors concluded that the 3'-terminal guanosine of the primer is the +1 template nucleotide. It states that the treatment will start with leutidine "C".

[0103] Another study by Ishikawa et al. m7 GpppApG, m7 Gppp m6 A p.G. m7 GpppA 2’Ome pG or m7 Gppp m6 A 2’Ome pG cap The primer oligonucleotide trimer is a 2'-deoxycytosine trinucleotide at template positions +1 and +2. The template had a nucleotide residue ("CC" template; Nucleic Acids Symposium um Series No. 53:129 (2009)) demonstrated that it can initiate transcription. The authors write: m7 Different results were obtained from the case using G5'pppG at the -1 position. So, m7 G5'pppN1pG with an additional adenosine (N1) in the T7 promoter "This may result from base pairing between the 2'-deoxythymidines in the nucleoside analogues." The method of claim 1, wherein the +1 and +2 nucleotides of the initial capped oligonucleotide trimer are This is distinct from the method described in the present invention, which pairs with the +1 and +2 nucleotides of the template. Ishikawa et al. used 6 mM of starting oligonucleotide trimer and 0.9 mM GTP and 7.5 mM each of ATP, CTP, and UTP were used. Competing to direct the transcription reaction toward capped RNA over pppRNA A greater than six-fold excess of capped initiating oligonucleotide primer over GTP was used. This is the most expensive nucleotide component of the transcription reaction and accounts for the total amount of synthesized RNA. On the other hand, low concentrations of GTP (0.9 mM) increase the RNA synthesis rate in the transcription reaction. Limiting the total yield (theoretically to less than 1.4 mg / mL). The method described in the paper provides efficient RNA capping and higher yields of RNA (2 ~6mg / mL), thus achieving high-quality mRNA production at a commercially viable cost. To enable production, it is not necessary to limit the concentration of any NTP.

[0104] None of the publications discussed above directly measured RNA capping efficiency. Therefore, the extent of capping in those studies is unknown.

[0105] Importantly, in all of the studies described above, the +1 template nucleotide was 2 '-deoxycytidine (Biochemistry Vol. 24: 5716-5723 (1985), Gene, vol. 112:101-105 (1992), Meth ods Mol.Biol. 74:99-110 (1997), Methods Mol.Biol. 252:9-17, (2004), Nucleic Ac ids Research Vol. 21: 1097-1101 (1993) Nucle ic Acids Symposium Series No. 53:129 (2009) ).

[0106] In the more than 20 years since the publication of transcription initiation studies using oligonucleotide primers, Ucleic Acids Symposium Series No. 53: 129(20 Until the publication of a short report in 2009, the initiation oligonucleotides containing 5'-to-5' inverted cap structures were There have been no published examples of transcription initiation using mononucleotide primers.

[0107] Methods and compositions provided herein for preparing 5'-capped RNA These include, but are not limited to, mRNA, small nuclear RNA (snRNA), and nucleolus Small RNAs (snoRNAs) and small Cajal body-specific RNAs (scaRNAs) are These methods involve the synthesis of RNA using DNA as a template and under the control of a promoter. For the cap-containing oligonucleotide primer, nucleoside 5'-triphosphate ( In certain embodiments, the method includes the use of RNA synthesis In particular, the initiating capped oligonucleotide provides utility in the synthesis of capped RNA. The initiation oligonucleotide primer is the same as that of the natural RNA molecule. Cap0, Cap1, Cap2 or TMG-cap-like structures, MG-cap is at the 5' position of the RNA, cap 1 at the 2nd position, and cap 2 at the 3rd position. The natural Cap 0 structure contains a 2'-O-methylated nucleoside unit adjacent to the It does not have any 2'-O-methylated nucleoside units.

[0108] Methods and compositions for preparing RNA include, but are not limited to, mRNA, snRNA, snoRNA, carrying modifications at or near the 5' end scaRNA, transfer RNA (tRNA), ribosomal RNA (rRNA) and These methods include DNA synthesis, DNA synthesis, and transfer-messenger RNA (tmRNA). A capped RNA template for promoter-controlled synthesis of RNA with or without an initiating oligonucleotide primer, nucleoside 5'-triphosphate ( In certain embodiments, the method includes the use of RNA synthesis In particular, structural modifications that provide utility in the synthesis of 5'-modified RNAs are provided. A modified starting oligonucleotide primer that retains the

[0109] The initiating capped oligonucleotide primer has a nucleotide at the 3' end of the primer. RNA polymerase-mediated synthesis of RNA on a DNA template by adding a dopamine unit Initiating Capped Oligonucleotides that have an open 3'-OH group to allow for the initiation of synthesis The primer is aligned to the transcription initiation site (i.e., the initiation site is close to the 3' end of the promoter sequence). (which may be adjacent to and overlap with the promoter sequence) and is substantially complementary to the template DNA sequence. In certain embodiments, the initial capped oligonucleotide primer is a primer It directs RNA synthesis primarily in one direction ("forward"), starting from the 3' end of the In some aspects and embodiments, the initiating capped oligonucleotide primer is outcompete any nucleoside 5'-triphosphate for initiation of synthesis, thereby Maximize the production of RNA starting with a capped oligonucleotide primer and 5'- It minimizes the production of RNA that starts with a triphosphate-nucleoside (usually GTP).

[0110] Production of mRNA by in vitro transcription is a promising strategy to produce highly active phage RNA polymerases. RNA polymerases use enzymes (T3, T7, SP6 and others) to amplify the template nucleic acid. The control of specific promoters incorporated into DNA plasmid constructs prior to the primer sequence. The transcription process usually begins with the synthesis of purine nucleoside 5'-triphosphates (usually GTP ) and RNA polymerase encounters a termination sequence or completes the DNA template. Continue until.

[0111] As discussed above, the mCAP dinucleotide analog contains Cap 0 7m G( 5')ppp(5')N is used for initiation of in vitro transcription (See, e.g., RNA vol. 1:957-967 (1995)). These dinucleotides Capped RNA molecules produced using the analogues contain Cap 0. However, Only about 50% of the synthesized capped RNA molecules were in the correct "forward" orientation with cap 0. To convert RNA with cap 0 to RNA with cap 1, , a further enzymatic reaction using (nucleoside-2'-O) methyltransferase However, this conversion may not be quantitative and may be difficult to control. It is not easy to separate the remaining cap 0 RNA from the cap 1 RNA. In addition, competition from NTPs (specifically, GTP) to initiate transcription is This further reduces the amount of active capped RNA molecules produced.

[0112] Additionally, modifications having blocked 3' and / or 2' positions on the ribose 7m G Retaining residues, 7m G 3’Ome (5')ppp(5')N and other related ARCs Modified dinucleotide analogs, such as the A analog, are used to initiate transcription in vitro. (For example, RNA Vol. 7: pp. 1486-1495 (2001)). ARCA cap analogs direct RNA synthesis only in the "forward" direction, Therefore, the 5' end ( 7m (with 2' and / or 3' modifications of G residues) This produces an RNA molecule with the standard dinucleotide analogs , 7m In comparison with RNA prepared using G(5')ppp(5')N, RNA with ARCA cap 0 is more active than RNA with ARCA cap 1. The dinucleotide analogs discussed so far are required to convert the nucleotide sequence into RNA that can be synthesized by the Further enzymatic reactions using similar (nucleoside-2'-O) methyltransferases This method has been described in detail for mCAP dinucleotide analogs. The ARCA cap of RNA with cap 0 has the same disadvantages as those described above. The conversion of 1 to RNA may not be quantitative, and the reaction is not easy to control. It is difficult to separate the remaining cap 0 RNA from the cap 1 RNA. Competition from NTPs (specifically, GTP) for the initiation of transcription increases the amount of active capsid produced. This further reduces the amount of loop-forming RNA molecules.

[0113] A short oligonucleotide primer (2-6 mer) with a 3'-terminal guanosine residue was used. , which has been used to initiate in vitro transcription (Pitulle, C. et al., Ge ne, vol. 112:101-105 (1992). The primers contained modified and unmodified ribonucleoside residues (e.g., modified ribonucleoside residues). The nucleoside residues are 2'-O-methylated nucleoside residues and 2'-deoxyribonucleic acid residues. (containing nucleotide residues). Shorter oligonucleotide primers (dimers to tetramers) The pentamer essentially outcompetes GTP for the initiation of transcription, allowing the longer primer (the ~hexamer) is significantly less efficient at initiating transcription than GTP. These longer primers (as they are designed) bind to the DNA template at the initiation site. In contrast, the dimer, AG (designed The nucleotide sequence (such as the nucleotide sequence of ... RNA molecules generated using oligonucleotide primers have internal 2'-O-methyl groups 5'-cap0, cap1, cap2 or TMG- The RNA that does not have a cap structure is designated as Cap 1, Cap 2, or Cap 3. or using a capping enzyme to convert RNA to a TMG-capped structure However, such a conversion can be carried out in the same manner as described above. It has the same disadvantages as those described above.

[0114] Other short nucleotides containing cap structures and internal 2'-O-methylated nucleoside residues RNA oligonucleotides have been prepared chemically (Ohkubo et al., Org. Le tters vol. 15: 4386-4389 (2013). These short cap shapes The synthetic oligonucleotides were ligated with T4 DNA ligase and complementary DNA sprinter oligos. The 5'-capped nucleotides are used to "decap" long RNAs ( The final RNA fragment synthesized using this chemical-enzymatic method was A has both an internal 2'-O-methylated nucleoside residue and a 5'-TMG-cap structure. However, using this ligation approach, Only synthetic RNA (<200mer) was prepared. Furthermore, the yields were low (15–30%). T4 DNA ligation reactions are not easy to control and optimize, and polyacrylamide gel electrophoresis is difficult. The laborious separation process using arylamide gel electrophoresis and the removal of residual caps The remaining capped RNA must be isolated from the uncapped RNA by PAGE. Long (500-10,000 bases) capped mRNA from uncapped mRNA Separation of the two is not feasible.

[0115] Finally, to initiate in vitro transcription of RNA, 5'-modified nucleosides or is a 5'-modified mononucleotide or dinucleotide, usually a derivative of guanosine has been used (Gene, vol. 112:101-105 (1992) and Bi Chem., 10371-378 (1999). The ether nucleosides and nucleotides can be coupled to a label or affinity group (e.g., biotin). When incorporated into the 5' end of the RNA, This 5'-labeled or tagged antibody will allow for easy detection, isolation and purification. Tagged RNA may be necessary for some applications. However, this strategy requires the use of capsids. To prepare mRNA with cap 0, cap 1, cap 2 or TMG-cap structures, Not used.

[0116] In certain embodiments of the present invention, the composition of the initial capped oligonucleotide primer of formula I In a related embodiment, the RNA comprises an initial capped oligonucleotide of formula I. This method uses a primer to synthesize the DNA.

[0117] Initiating Capped Oligonucleotide Primer The initiation capped oligonucleotide primer of the present invention is a capped oligonucleotide primer that is capable of binding to a DNA template at the initiation site. The hybridization sequence may be complementary to the sequence provided herein. Hybridization sequences of primers for use in the methods and compositions described herein The length of the primer depends on the identity of the template nucleotide sequence and whether the primer is capable of in vitro transcription. During transcription, the DNA template hybridizes to the nuclease, depending on several factors, including the temperature used. The initiating capped oligonucleotide primer for use in transcription Determination of the desired length of a specific nucleotide sequence can be accomplished by one of ordinary skill in the art or through routine experimentation. For example, the length of the nucleic acid or oligonucleotide can be readily determined by the desired hybridization. The determination can be based on redization specificity or selectivity.

[0118] In some embodiments, the initiating capped oligonucleotide primer (inverted 5'- The nucleotide length of the 5' cap nucleotide (including the 5' cap nucleotide) is between 3 and about 9, with some In this embodiment, the nucleic acid of the initiating capped oligonucleotide primer (including the cap) The nucleotide length is between 3 and about 7, and in some embodiments, the initial capped oligo the nucleotide primer (including the cap) is between 3 and about 5 nucleotides in length; In some embodiments, the initial capped oligonucleotide primer (including the cap) The length of the initial capped oligonucleotide primer is approximately 3 nucleotides. The length of the hybridization sequence is determined by the length of the initiating capped oligonucleotide primer. The length of the slit may be less than or equal to the total length of the slit.

[0119] The presence of the hybridization sequence indicates that the initiating capped oligonucleotide primer , complementary to the DNA template at the initiation site only in the desired orientation (i.e., the "forward" orientation) In the forward orientation, the RNA transcripts are aligned primarily with inverted guanosine residues. (i.e. 7m G(5')ppp(5')N) over the incorrect "reverse" direction The predominance of forward primer alignment on the DNA template (Figure 1) is a key factor in the hybridization of The latter is maintained by the thermodynamics of the initial capped oligonucleotide. The length of the hybridization sequence of the nucleotide primer and the hybridization with the DNA template The desired forward orientation is determined by the identity of the bases involved in the redization. Hybridization occurs during in vitro transcription, when the DNA template and the initiation capsid are hybridized. The temperature at which the oligonucleotide primers are hybridized or used and It may also vary depending on the reaction conditions.

[0120] The initiating capped oligonucleotide primer of the present invention has the standard GTP, ATP, CT It enhances the efficiency of transcription initiation compared to the efficiency of initiation with P or UTP. In this embodiment, initiation of transcription occurs when synthesis of RNA does not occur from any NTP in the transcription mixture. It is not enhanced primarily when starting from an initial capped oligonucleotide primer. It is believed that the increased efficiency of transcription initiation leads to higher yields of RNA transcripts. The enhanced efficiency of transcription initiation was observed using conventional methods without an initiating capped primer. The synthesis of RNA was increased by approximately 10%, 20%, 40%, 60%, 80%, 90%, and 1 The amount of the ion exchange reaction may be increased by more than about 100%, about 150%, about 200%, or about 500%. In this embodiment, the "initiation capped oligonucleotide primer" is an arbitrary primer for initiation of transcription. The initiating capped oligonucleotide is then introduced into the ribosome to outcompete the NTP (including GTP). The level of substrate activity and efficacy of the tide primers can be readily determined. An example of a method for this is illustrated in Example 13. In certain embodiments, initiation is by NTP. This occurs from capped oligonucleotide primers rather than from siRNA, which results in higher levels of It results in the capping of the transcribed mRNA.

[0121] In some embodiments, the RNA comprises an initiating capped oligonucleotide having a substitution or modification. In some embodiments, a method is provided in which the primer is synthesized using an initiating capped primer. Substitutions and modifications of oligonucleotide primers do not substantially impair RNA synthesis A routine test synthesis was carried out to synthesize the modified initiating capped oligonucleotide primer. It can be examined whether the desired synthesis result can be obtained using the above method. Conducting such routine experiments to see whether the desired results can be obtained Substitutions or modifications of the initial capped oligonucleotide primer can be, for example: one or more modified nucleoside bases, one or more modified sugars, one or more or more modified internucleotide linkages and / or one or more modified triplet Contains phosphate bridges.

[0122] The methods and compositions provided herein may include one or more modifying groups. The modified initiating capped oligonucleotide primer is By incorporating into the initiation site, it can be extended by RNA polymerase on the DNA template. Capped oligonucleotide primers are made up of natural RNA and DNA nucleosides, modified The initial capped oligonucleotide may include a nucleoside or nucleoside analog. The nucleotide primer may be a naturally occurring internucleotide phosphodiester linkage or a modification thereof. It may contain combinations of these.

[0123] In one embodiment, the modifying group is modified at an increasing rate as the temperature of the enzyme reaction medium is increased.

[0124] In some embodiments, at least one of the nucleotides may have a modification as disclosed herein. The method proposed here is that RNA is synthesized when one or more NTPs are added to the transcription reaction. In some embodiments, the modification of at least one NTP is RNA polymerase-mediated The modification of NTPs may, for example, include one or more modifications. modified nucleoside base, one or more modified sugars, one or more modified The modified NTP may include a 5'-triphosphate. It can be incorporated into the 3' end of the primer, does not block transcription, and supports further extension of the primer. Hold.

[0125] In another embodiment, the modification group of the initial capped oligonucleotide primer is a detectable Thus, after transcription, a detectable label or a detectable marker may be added. Target RNA containing the marker or markers is identified by size, mass, color and / or affinity capture. In some embodiments, the detectable label or marker is a fluorescent dye. and the affinity capture label is biotin. In certain embodiments, one or more of the transcription reactions contains multiple components (initial capped oligonucleotide primer and / or NTPs) Thus, after transcription, the RNA molecule can be identified, for example, by size, mass, affinity capture, or color. In one embodiment, the detectable label is a fluorescent dye and the affinity capture label is biotin.

The transcript was transcribed from a template having the following structure: m7 GpppA 2’Ome pG start oligo If the nucleotide is perfectly complementary to the +1 and +2 nucleotides, then The main products were: m7 GpppA 2’Ome The desired template starting with pG was used The transcript was the ChAP1 transcript (Figures 12A and 12B). The capping efficiency was estimated using the formula (intensity of the capped peak) / [(capped The primer was used to measure the intensity of the 5'OH peak (intensity of the 5'OH peak formed) + (intensity of the 5'OH peak). The capping efficiencies using primer / NTP formulation 2 and primer / NTP formulation 3 were 99% and 96%. Only a few abnormal initiation products were detected.

"|" indicates a capped open Note that this indicates the base pairing of the initial nucleotide with the template nucleotide. In the second register, the 3' guanosine-initiated template nucleotide positions are shown. The capped oligonucleotide residue pairs with the +2 template cytidine and the +1 initiator cap The adenosine-tagged oligonucleotide forms a perfect hybrid with the +1 template nucleotide This is because the template 5' guanosine is replaced with a non-template adenosine. The capping efficiency was estimated using the following formula: Intensity of capped peak (cap 1+A) + (cap 1G to A) / [(cap Intensity of capped peaks (cap1+A) + (cap1G to A) + (5' The calculated capacitance in Figures 13C and 13D was calculated using the intensity of the OH peak. The capping efficiency was 97 and 77%. The fidelity of transcription initiation measured was determined by the initiation capped oligonucleotide primers. The surprising result was that the DNA fragments were quite highly complementary to the +1 and +2 nucleotides of the template. Furthermore, our method allows us to identify the NTP that drives cap formation. Efficient capping can be achieved without reducing the concentration of ribozyme, allowing for much higher transcription yields. Therefore, the capping method described by the present inventors is similar to that of Ishikawa et al. It is different from and superior to the EXAMPLES
