[0242] Construction of Nucleic Acids

[0243] The isolated nucleic acids of the disclosure can be made using (a) recombinant methods, (b) synthetic techniques, (c) purification techniques, and / or (d) combinations thereof, as well- known in the art.

[0244] The nucleic acids can conveniently comprise sequences in addition to a polynucleotide of the present disclosure. For example, a multi-cloning site comprising one or more endonuclease restriction sites can be inserted into the nucleic acid to aid in isolation of the polynucleotide. Also, translatable sequences can be inserted to aid in the isolation of the translated polynucleotide of the disclosure. For example, a hexa-histidine marker sequence provides a convenient means to purify the proteins of the disclosure. The nucleic acid of the disclosure, excluding the coding sequence, is optionally a vector, adapter, or linker for cloning and / or expression of a polynucleotide of the disclosure.

[0245] Additional sequences can be added to such cloning and / or expression sequences to optimize their function in cloning and / or expression, to aid in isolation of the polynucleotide, or to improve the introduction of the polynucleotide into a cell. Use of cloning vectors, expression vectors, adapters, and linkers is well known in the art. (See, e.g. Ausubel. supra; or Sambrook, supra).

[0246] Recombinant Methods for Constructing Nucleic Acids

[0247] The isolated nucleic acid compositions of this disclosure, such as RNA, cDNA, genomic DNA, or any combination thereof, can be obtained from biological sources using any number of cloning methodologies known to those of skill in the art. In some aspects, oligonucleotide probes that selectively hybridize, under stringent conditions, to the polynucleotides of the present disclosure are used to identify the desired sequence in a cDNA or genomic DNA library. The isolation of RNA, and construction of cDNA and genomic libraries are well known to those of ordinary' skill in the art. (See, e.g., Ausubel, supra; or Sambrook, supra).

[0248] Nucleic Acid Screening and Isolation Methods

[0249] A cDNA or genomic library can be screened using a probe based upon the sequence of a polynucleotide of the disclosure. Probes can be used to hybridize with genomic DNA or cDNA sequences to isolate homologous genes in the same or different organisms. Those of skill in the art will appreciate that various degrees of stringency of hybridization can be employed in the assay; and either the hybridization or the wash medium can be stringent. As the conditions for hybridization become more stringent, there must be a greater degree of complementarity7between the probe and the target for duplex formation to occur. The degree of stringency can be controlled by one or more of temperature, ionic strength, pH and the presence of a partially denaturing solvent, such as formamide. For example, the stringency of hybridization is conveniently varied by changing the polarity of the reactant solution through, for example, manipulation of the concentration of formamide within the range of 0% to 50%. The degree of complementarity' (sequence identity) required for detectable binding will vary' in accordance with the stringency of the hybridization medium and / or wash medium. The degree of complementarity will optimally be 100%, or 70-100%, or any range or value therein. However, it should be understood that minor sequence variations in the probes and primers can be compensated for by reducing the stringency of the hybridization and / or wash medium.

[0250] Methods of amplification of RNA or DNA are well known in the art and can be used according to the disclosure without undue experimentation, based on the teaching and guidance presented herein.

[0251] Known methods of DNA or RNA amplification include, but are not limited to, polymerase chain reaction (PCR) and related amplification processes (see, e.g., U.S. Pat. Nos. 4,683,195, 4,683,202, 4,800,159, 4,965,188, to Mullis, et al.; 4,795,699 and 4,921,794 to Tabor, et al; 5,142,033 to Innis; 5,122,464 to Wilson, et al.; 5,091,310 to Innis; 5,066,584 to Gyllensten, et al; 4,889,818 to Gelfand, et al; 4,994,370 to Silver, et al; 4,766.067 to Biswas; 4,656,134 to Ringold) and RNA mediated amplification that uses anti-sense RNA to the target sequence as a template for double-stranded DNA synthesis (U.S. Pat. No. 5,130,238 to Malek, et al, with the tradename NASBA), the entire contents of which references are incorporated herein by reference. (See, e.g., Ausubel. supra, or Sambrook, supra.}

[0252] For instance, polymerase chain reaction (PCR) technology can be used to amplify the sequences of polynucleotides of the disclosure and related genes directly from genomic DNAor cDNA libraries. PCR and other in vitro amplification methods can also be useful, for example, to clone nucleic acid sequences that code for proteins to be expressed, to make nucleic acids to use as probes for detecting the presence of the desired mRNA in samples, for nucleic acid sequencing, or for other purposes. Examples of techniques sufficient to direct persons of skill through in vitro amplification methods are found in Berger, supra, Sambrook, supra, and Ausubel, supra, as well as Mullis, et al., U.S. Pat. No. 4,683,202 (1987); and Innis, et al.. PCR Protocols A Guide to Methods and Applications, Eds., Academic Press Inc., San Diego, Calif. (1990). Commercially available kits for genomic PCR amplification are known in the art. See, e.g., Advantage-GC Genomic PCR Kit (Clontech). Additionally, e.g., the T4 gene 32 protein (Boehringer Mannheim) can be used to improve yield of long PCR products.

[0253] Synthetic Methods for Constructing Nucleic Acids

[0254] The isolated nucleic acids of the disclosure can also be prepared by direct chemical synthesis by known methods (see, e.g, Ausubel, et al., supra). Chemical synthesis generally produces a single-stranded oligonucleotide, which can be converted into double-stranded DNA by hybridization with a complementary sequence, or by polymerization with a DNA polymerase using the single strand as a template. One of skill in the art will recognize that while chemical synthesis of DNA can be limited to sequences of about 100 or more bases, longer sequences can be obtained by the ligation of shorter sequences.

[0255] Recombinant Expression Cassettes

[0256] The disclosure further provides recombinant expression cassettes comprising a nucleic acid of the disclosure. A nucleic acid sequence of the disclosure can be used to construct a recombinant expression cassette that can be introduced into at least one desired host cell. A recombinant expression cassette will typically comprise a polynucleotide of the disclosure operably linked to transcriptional initiation regulatory sequences that will direct the transcription of the polynucleotide in the intended host cell. Both heterologous and non- heterologous (i.e., endogenous) promoters can be employed to direct expression of the nucleic acids of the disclosure.

[0257] In some aspects, isolated nucleic acids that serve as promoter, enhancer, or other elements can be introduced in the appropriate position (upstream, downstream or in the intron) of a non-heterologous form of a polynucleotide of the disclosure so as to up or down regulateexpression of a polynucleotide of the disclosure. For example, endogenous promoters can be altered in vivo or in vitro by mutation, deletion and / or substitution.

[0258] Expression Vectors and Host Cells

[0259] The disclosure also relates to vectors that include isolated nucleic acid molecules of the disclosure and host cells that are genetically engineered with the recombinant vectors, as is well known in the art. See, e.g, Sambrook, et al., supra-, Ausubel, et al., supra, each entirely incorporated herein by reference.

[0260] The polynucleotides can optionally be joined to a vector containing a selectable marker for propagation in a host. Generally, a plasmid vector is introduced in a precipitate, such as a calcium phosphate precipitate, or in a complex with a charged lipid. If the vector is a vims, it can be packaged in vitro using an appropriate packaging cell line and then transduced into host cells.

[0261] The DNA insert should be operatively linked to an appropriate promoter. The expression constructs will further contain sites for transcription initiation, termination and, in the transcribed region, a ribosome binding site for translation. The coding portion of the mature transcripts expressed by the constructs will preferably include a translation initiating at the beginning and a termination codon (e.g., UAA, UGA or UAG) appropriately positioned at the end of the mRNA to be translated, with UAA and UAG preferred for mammalian or eukaryotic cell expression.

[0262] Expression vectors will preferably but optionally include at least one selectable marker. Such markers include, e.g., but are not limited to, ampicillin, zeocin (Sh bla gene), puromycin (pac gene), hygromycin B (hygB gene), G418 / Geneticin (neo gene), DHFR (encoding Dihydrofolate Reductase and conferring resistance to Methotrexate), mycophenolic acid, or glutamine synthetase (GS, U.S. Pat. Nos. 5,122,464; 5,770,359; 5,827,739), blasticidin (bsd gene), resistance genes for eukaryotic cell culture as well as ampicillin, zeocin (Sh bla gene), puromycin (pac gene), hygromycin B (hygB gene), G418 / Geneticin (neo gene), kanamycin, spectinomycin. streptomycin, carbenicillin, bleomycin, erythromycin, polymyxin B. or tetracycline resistance genes for culturing in E. coli and other bacteria or prokaryotics (the above patents are entirely incorporated hereby by reference). Appropriate culture mediums and conditions for the above-described host cells are known in the art. Suitable vectors will be readily apparent to the skilled artisan. Introduction of a vector construct into a host cell can beeffected by calcium phosphate transfection, DEAE-dextran mediated transfection, cationic lipid-mediated transfection, electroporation, transduction, infection or other known methods. Such methods are described in the art, such as Sambrook, supra. Chapters 1-4 and 16-18; Ausubel, supra, Chapters 1, 9, 13, 15, 16.

[0263] Expression vectors will preferably but optionally include at least one selectable cell surface marker for isolation of cells modified by the compositions and methods of the disclosure. Selectable cell surface markers of the disclosure comprise surface proteins, glycoproteins, or group of proteins that distinguish a cell or subset of cells from another defined subset of cells. Preferably the selectable cell surface marker distinguishes those cells modified by a composition or method of the disclosure from those cells that are not modified by a composition or method of the disclosure. Such cell surface markers include, e.g., but are not limited to, ‘‘cluster of designation” or “classification determinant” proteins (often abbreviated as “CD”) such as a truncated or full length form of CD19, CD271, CD34, CD22, CD20, CD33, CD52, or any combination thereof. Cell surface markers further include the suicide gene marker RQR8 (Philip B et al. Blood. 2014 Aug 21; 124(8): 1277-87).

[0264] Expression vectors will preferably but optionally include at least one selectable drug resistance marker for isolation of cells modified by the compositions and methods of the disclosure. Selectable drug resistance markers of the disclosure may comprise wild-type or mutant Neo, DHFR, TYMS, FRANCE, RAD51C, GCS, MDR1, ALDH1, NKX2.2, or any combination thereof.

[0265] Those of ordinary skill in the art are knowledgeable in the numerous expression systems available for expression of a nucleic acid molecule encoding a protein of the disclosure.

[0266] Definitions

[0267] As used throughout the disclosure, the singular forms “a,” “and,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a method” includes a plurality of such methods and reference to “a dose” includes reference to one or more doses and equivalents thereof known to those skilled in the art, and so forth.

[0268] The term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, e.g.. the limitations of the measurement system. Forexample, “about'’ can mean within 1 or more standard deviations. Alternatively, “about” can mean a range of up to 20%, or up to 10%. or up to 5%, or up to 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, preferably within 5-fold, and more preferably within 2-fold, of a value. Where particular values are described in the application and claims, unless otherw ise stated the term “about” meaning within an acceptable error range for the particular value should be assumed.

[0269] In the chemical formulas shown herein, the marking indicates the position where a functional group bonds to another portion of a molecule. Definitions of specific functional groups and chemical terms are described in more detail below.

[0270] Certain compounds of the present invention may exist in particular geometric or stereoisomeric forms. The present invention contemplates all such compounds, including cis- and trans-isomers, R- and S-enantiomers, diastereomers, (D)-isomers, (L)-isomers, the racemic mixtures thereof, and other mixtures thereof, as falling within the scope of the invention. Additional asymmetric carbon atoms may be present in a substituent such as an alkyl group. All such isomers, as well as mixtures thereof, are intended to be included in this invention.

[0271] Isomeric mixtures containing any of a variety of isomer ratios may be utilized in accordance with the present invention. For example, where only two isomers are combined, mixtures containing 50:50, 60:40. 70:30, 80:20, 90: 10. 95:5. 96:4. 97:3. 98:2. 99: 1. or 100:0 isomer ratios are all contemplated by the present invention. Those of ordinary' skill in the art will readily appreciate that analogous ratios are contemplated for more complex isomer mixtures.

[0272] If, for instance, a particular enantiomer of a compound of the present invention is desired, it may be prepared by asymmetric synthesis, or by derivation with a chiral auxiliary', where the resulting diastereomeric mixture is separated and the auxiliary group cleaved to provide the pure desired enantiomers. Alternatively, where the molecule contains a basic functional group, such as amino, or an acidic functional group, such as carboxyl, diastereomeric salts are formed with an appropriate optically -active acid or base, followed by resolution of the diastereomers thus formed by fractional crystallization or chromatographic means well known in the art, and subsequent recovery of the pure enantiomers.

[0273] One of ordinary skill in the art will appreciate that the synthetic methods, as described herein, utilize a variety of protecting groups. By the term "protecting group," as used herein, it is meant that a particular functional moiety, e.g., O, S, or N, is temporarily blocked so that a reaction can be carried out selectively at another reactive site in a multifunctional compound. In certain embodiments, a protecting group reacts selectively in good yield to give a protected substrate that is stable to the projected reactions: the protecting group should be selectively removable in good yield by readily available, preferably non-toxic reagents that do not attack the other functional groups; the protecting group forms an easily separable derivative (more preferably without the generation of new stereogenic centers); and the protecting group has a minimum of additional functionality to avoid further sites of reaction. As detailed herein, oxygen, sulfur, nitrogen, and carbon protecting groups may be utilized.

[0274] The term "aliphatic," as used herein, includes both saturated and unsaturated, straight chain (i.e., unbranched), branched, acyclic, cyclic, or polycyclic aliphatic hydrocarbons, which are optionally substituted with one or more functional groups. As will be appreciated by one of ordinary skill in the art, "aliphatic" is intended herein to include, but is not limited to, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and cycloalkynyl moieties.

[0277] The term "alkenyl" refers to an unsaturated straight or, when applicable, branched chain aliphatic group with one or more carbon-carbon double bonds, having from 2 to 18 carbon atoms. As such, "alkenyl" encompasses C2, C3, C4, C5, C6, C7, C8, C9, C10, C11and C12groups. Alkenyl groups include, for example, ethenyl, propenyl, butenyl, l-methyl-2-buten-l-yl, and the like.

[0278] The term "alkynyl" refers to an unsaturated straight or, when applicable, branched chain aliphatic group with one or more carbon-carbon triple bonds, having from 2 to 18 carbon atoms.

[0282] It will be understood that the compounds of any one of the Formulae disclosed herein and any pharmaceutically acceptable salts thereof, comprise stereoisomers, mixtures of stereoisomers, polymorphs of all isomeric forms of said compounds.

[0283] The term "independently selected" is used herein to indicate that the R groups can be identical or different.

[0284] The term "substituted," whether preceded by the term "optionally" or not, and "substituent," as used herein, refer to the ability, as appreciated by one skilled in this art, to change one functional group for another functional group provided that the valency of all atoms is maintained. When more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. The substituents may also be further substituted (e.g., an aryl group substituent may have another substituent off it, such as another aryl group, which is further substituted with fluorine at one or more positions).

[0285] The disclosure provides isolated or substantially purified polynucleotide or protein compositions. An "isolated" or "purified" polynucleotide or protein, or biologically active portion thereof, is substantially or essentially free from components that normally accompany or interact with the polynucleotide or protein as found in its naturally occurring environment. Thus, an isolated or purified polynucleotide or protein is substantially free of other cellular material or culture medium when produced by recombinant techniques, or substantially free of chemical precursors or other chemicals when chemically synthesized. Optimally, an "isolated" polynucleotide is free of sequences (optimally protein encoding sequences) that naturally flank the polynucleotide (i.e., sequences located at the 5' and 3' ends of the polynucleotide) in the genomic DNA of the organism from which the polynucleotide is derived. For example, in various aspects, the isolated polynucleotide can contain less than about 5 kb, 4 kb, 3 kb, 2 kb, 1 kb, 0.5 kb, or 0.1 kb of nucleotide sequence that naturally flank the polynucleotide in genomic DNA of the cell from which the polynucleotide is derived. A protein that is substantially free of cellular material includes preparations of protein having less than about 30%, 20%, 10%, 5%, or 1% (by dry weight) of contaminating protein. When the protein of the disclosure or biologically active portion thereof is recombinantly produced, optimally culture mediumrepresents less than about 30%, 20%, 10%, 5%, or 1% (by dry weight) of chemical precursors or non-protein-of-interest chemicals.

[0286] The disclosure provides fragments and variants of the disclosed DNA sequences and proteins encoded by these DNA sequences. As used throughout the disclosure, the term "fragment" refers to a portion of the DNA sequence or a portion of the amino acid sequence and hence protein encoded thereby. Fragments of a DNA sequence comprising coding sequences may encode protein fragments that retain biological activity of the native protein and hence DNA recognition or binding activity to a target DNA sequence as herein described. Alternatively, fragments of a DNA sequence that are useful as hybridization probes generally do not encode proteins that retain biological activity or do not retain promoter activity. Thus, fragments of a DNA sequence may range from at least about 20 nucleotides, about 50 nucleotides, about 100 nucleotides, and up to the full-length polynucleotide of the disclosure.

[0287] Nucleic acids or proteins of the disclosure can be constructed by a modular approach including preassembling monomer units and / or repeat units in target vectors that can subsequently be assembled into a final destination vector. Polypeptides of the disclosure may comprise repeat monomers of the disclosure and can be constructed by a modular approach by preassembling repeat units in target vectors that can subsequently be assembled into a final destination vector. The disclosure provides polypeptides produced by this method as well as nucleic acid sequences encoding these polypeptides. The disclosure provides host organisms and cells comprising nucleic acid sequences encoding polypeptides produced by this modular approach.

[0288] The term "antibody" is used in the broadest sense and specifically covers single monoclonal antibodies (including agonist and antagonist antibodies) and antibody compositions with poly epitopic specificity. It is also within the scope hereof to use natural or synthetic analogs, mutants, variants, alleles, homologs and orthologs (herein collectively referred to as “analogs”) of the antibodies hereof as defined herein. Thus, according to an aspect hereof, the term “antibody hereof’ in its broadest sense also covers such analogs. Generally, in such analogs, one or more amino acid residues may have been replaced, deleted and / or added, compared to the antibodies hereof as defined herein.

[0289] The term "comprising" is intended to mean that the compositions and methods include the recited elements, but do not exclude others. "Consisting essentially of’ when used to definecompositions and methods, shall mean excluding other elements of any essential significance to the combination when used for the intended purpose. Thus, a composition consisting essentially of the elements as defined herein would not exclude trace contaminants or inert carriers. "Consisting of’ shall mean excluding more than trace elements of other ingredients and substantial method steps. Aspects defined by each of these transition terms are within the scope of this disclosure.

[0290] As used herein, "expression" refers to the process by which polynucleotides are transcribed into mRNA and / or the process by which the transcribed mRNA is subsequently translated into peptides, polypeptides, or proteins. If the polynucleotide is derived from genomic DNA. expression may include splicing of the mRNA in a eukaryotic cell.

[0291] “Gene expression” refers to the conversion of the information, contained in a gene, into a gene product. A gene product can be the direct transcriptional product of a gene (e.g., mRNA, tRNA, rRNA, antisense RNA, ribozyme, shRNA, micro RNA, structural RNA or any other type of RNA) or a protein produced by translation of an mRNA. Gene products also include RNAs which are modified, by processes such as capping, polyadenylation, methylation, and editing, and proteins modified by, for example, methylation, acetylation, phosphorylation, ubiquitination, ADP-ribosylation, myristilation, and glycosylation.

[0292] “Modulation” or “regulation” of gene expression refers to a change in the activity of a gene. Modulation of expression can include, but is not limited to, gene activation and gene repression.

[0293] The term “operatively linked” or its equivalents (e.g., “linked operatively”) means two or more molecules are positioned with respect to each other such that they are capable of interacting to affect a function attributable to one or both molecules or a combination thereof.

[0294] Non-covalently linked components and methods of making and using non-covalently linked components, are disclosed. The various components may take a variety of different forms as described herein. For example, non-covalently linked (i.e.. operatively linked) proteins may be used to allow temporary interactions that avoid one or more problems in the art. The ability of non-covalently linked components, such as proteins, to associate and dissociate enables a functional association only or primarily under circumstances where such association is needed for the desired activity. The linkage may be of duration sufficient to allow the desired effect.

[0295] A method for directing proteins to a specific locus in a genome of an organism is disclosed. The method may comprise the steps of providing a DNA localization component and providing an effector molecule, wherein the DNA localization component and the effector molecule are capable of operatively linking via a non-covalent linkage.

[0296] A “target site” or “target sequence” is a nucleic acid sequence that defines a portion of a nucleic acid to which a binding molecule will bind, provided sufficient conditions for binding exist.

[0297] The terms "nucleic acid" or "oligonucleotide" or "polynucleotide" refer to at least two nucleotides covalently linked together. The depiction of a single strand also defines the sequence of the complementary strand. Thus, a nucleic acid may also encompass the complementary strand of a depicted single strand. A nucleic acid of the disclosure also encompasses substantially identical nucleic acids and complements thereof that retain the same structure or encode for the same protein.

[0298] Probes of the disclosure may comprise a single stranded nucleic acid that can hybridize to a target sequence under stringent hybridization conditions. Thus, nucleic acids of the disclosure may refer to a probe that hybridizes under stringent hybridization conditions.

[0299] Nucleic acids of the disclosure may be single- or double-stranded. Nucleic acids of the disclosure may contain double-stranded sequences even when the majority of the molecule is single-stranded. Nucleic acids of the disclosure may contain single-stranded sequences even when the majority of the molecule is double-stranded. Nucleic acids of the disclosure may include genomic DNA, cDNA, RNA, or a hybrid thereof. Nucleic acids of the disclosure may contain combinations of deoxyribo- and ribo-nucleotides. Nucleic acids of the disclosure may contain combinations of bases including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine hypoxanthine, isocytosine and isoguanine. Nucleic acids of the disclosure may be synthesized to comprise non-natural amino acid modifications. Nucleic acids of the disclosure may be obtained by chemical synthesis methods or by recombinant methods.

[0300] Nucleic acids of the disclosure, either their entire sequence, or any portion thereof, may be non-naturally occurring. Nucleic acids of the disclosure may contain one or more mutations, substitutions, deletions, or insertions that do not naturally-occur, rendering the entire nucleic acid sequence non-naturally occurring. Nucleic acids of the disclosure may contain one or more duplicated, inverted or repeated sequences, the resultant sequence of which does not naturally-occur, rendering the entire nucleic acid sequence non-naturally occurring. Nucleic acids of the disclosure may contain modified, artificial, or synthetic nucleotides that do not naturally-occur, rendering the entire nucleic acid sequence non-naturally occurring.

[0301] Given the redundancy in the genetic code, a plurality of nucleotide sequences may encode any particular protein. All such nucleotide sequences are contemplated herein.

[0302] As used throughout the disclosure, the term "operably linked" refers to the expression of a gene that is under the control of a promoter with which it is spatially connected. A promoter can be positioned 5' (upstream) or 3' (downstream) of a gene under its control. The distance between a promoter and a gene can be approximately the same as the distance between that promoter and the gene it controls in the gene from which the promoter is derived. Variation in the distance between a promoter and a gene can be accommodated without loss of promoter function.

[0303] As used throughout the disclosure, the term "promoter" refers to a synthetic or naturally- derived molecule that is capable of conferring, activating or enhancing expression of a nucleic acid in a cell. A promoter can comprise one or more specific transcriptional regulatory sequences to further enhance expression and / or to alter the spatial expression and / or temporal expression of same. A promoter can also comprise distal enhancer or repressor elements, which can be located as much as several thousand base pairs from the start site of transcription. A promoter can be derived from sources including viral, bacterial, fungal, plants, insects, and animals. A promoter can regulate the expression of a gene component constitutively or differentially with respect to the cell, the tissue or the organ in which expression occurs or, with respect to the developmental stage at which expression occurs, or in response to external stimuli such as physiological stresses, pathogens, metal ions, or inducing agents. Representative examples of promoters include the bacteriophage T7 promoter, bacteriophage T3 promoter. SP6 promoter, lac operator-promoter, tac promoter, SV40 late promoter, SV40 early promoter, RSV-LTR promoter, CMV IE promoter, EF-1 Alpha promoter, CAG promoter, SV40 early promoter or SV40 late promoter and the CMV IE promoter.

[0304] As used throughout the disclosure, the term “substantially complementary" refers to a first sequence that is at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98% or 99% identical to the complement of a second sequence over a region of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 30. 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100,180, 270, 360, 450, 540, or more nucleotides or amino acids, or that the two sequences hybridize under stringent hybridization conditions.

[0305] As used throughout the disclosure, the term "substantially identical" refers to a first and second sequence are at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98% or 99% identical over a region of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. 21. 22. 23, 24, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 180, 270, 360, 450, 540 or more nucleotides or amino acids, or with respect to nucleic acids, if the first sequence is substantially complementary to the complement of the second sequence.

[0306] As used throughout the disclosure, the term "variant" when used to describe a nucleic acid, refers to (i) a portion or fragment of a referenced nucleotide sequence; (ii) the complement of a referenced nucleotide sequence or portion thereof; (iii) a nucleic acid that is substantially identical to a referenced nucleic acid or the complement thereof; or (iv) a nucleic acid that hybridizes under stringent conditions to the referenced nucleic acid, complement thereof, or a sequences substantially identical thereto.

[0307] As used throughout the disclosure, the term "vector" refers to a nucleic acid sequence containing an origin of replication. A vector can be a viral vector, bacteriophage, bacterial artificial chromosome or yeast artificial chromosome. A vector can be a DNA or RNA vector. A vector can be a self-replicating extrachromosomal vector, and preferably, is a DNA plasmid. A vector may comprise a combination of an amino acid with a DNA sequence, an RNA sequence, or both a DNA and an RNA sequence.

[0308] As used throughout the disclosure, the term "variant" when used to describe a peptide or polypeptide, refers to a peptide or polypeptide that differs in amino acid sequence by the insertion, deletion, or conservative substitution of amino acids, but retains at least one biological activity. “Variant"’ can also mean a protein with an amino acid sequence that is substantially identical to a referenced protein with an amino acid sequence that retains at least one biological activity.

[0309] A conservative substitution of an amino acid, i.e., replacing an amino acid with a different amino acid of similar properties (e.g., hydrophilicity, degree and distribution of charged regions) is recognized in the art as typically involving a minor change. These minor changes can be identified, in part, by considering the hydropathic index of amino acids, as understood in the art. Kyte et al., J. Mol. Biol. 157: 105-132 (1982). The hydropathic index ofan amino acid is based on a consideration of its hydrophobicity and charge. Amino acids of similar hydropathic indexes can be substituted and still retain protein function. In an aspect, amino acids having hydropathic indexes of ±2 are substituted. The hydrophilicity of amino acids can also be used to reveal substitutions that would result in proteins retaining biological function. A consideration of the hydrophilicity of amino acids in the context of a peptide permits calculation of the greatest local average hydrophilicity of that peptide, a useful measure that has been reported to correlate well with antigenicity and immunogenicity. U.S. Patent No. 4,554,101, incorporated fully herein by reference.

[0310] Substitution of amino acids having similar hydrophilicity values can result in peptides retaining biological activity, for example, immunogenicity. Substitutions can be performed with amino acids having hydrophilicity values within ±2 of each other. Both the hydrophobicity index and the hydrophilicity value of amino acids are influenced by the particular side chain of that amino acid. Consistent with that observation, amino acid substitutions that are compatible with biological function are understood to depend on the relative similarity of the amino acids, and particularly the side chains of those amino acids, as revealed by the hydrophobicity, hydrophilicity, charge, size, and other properties.

[0311] As used herein, "‘conservative’' amino acid substitutions may be defined as set out in Tables 1, 2, or 3 below. In some aspects, fusion polypeptides and / or nucleic acids encoding such fusion polypeptides include conservative substitutions that have been introduced by modification of polynucleotides encoding polypeptides of the disclosure. Amino acids can be classified according to physical properties and contribution to secondary and tertiary protein structure. A conservative substitution is a substitution of one amino acid for another amino acid that has similar properties. Exemplary conservative substitutions are set out in Table 1.

[0312] Table 1 - Conservative Substitutions I

[0313] Alternately, conservative amino acids can be grouped as described in Lehninger, (Biochemistry, Second Edition; Worth Publishers, Inc. NY, N.Y. (1975), pp. 71-77) as set forth in Table 2.

[0314] Table 2 - Conservative Substitutions II

[0315] Alternately, exemplary conservative substitutions are set out in Table 3.

[0316] Table 3 - Conservative Substitutions III

[0317] It should be understood that the polypeptides of the disclosure are intended to include polypeptides bearing one or more insertions, deletions, or substitutions, or any combination thereof, of amino acid residues as well as modifications other than insertions, deletions, or substitutions of amino acid residues. Polypeptides or nucleic acids of the disclosure may contain one or more conservative substitution.

[0318] As used throughout the disclosure, the term ‘'more than one” of the aforementioned amino acid substitutions refers to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 or more of the recited amino acid substitutions. The term “more than one” may refer to 2, 3, 4, or 5 of the recited amino acid substitutions.

[0319] Polypeptides and proteins of the disclosure, either their entire sequence, or any portion thereof, may be non-naturally occurring. Polypeptides and proteins of the disclosure may contain one or more mutations, substitutions, deletions, or insertions that do not naturally occur, rendering the entire amino acid sequence non-naturally occurring. Polypeptides and proteins of the disclosure may contain one or more duplicated, inverted or repeated sequences, the resultant sequence of which does not naturally occur, rendering the entire amino acid sequence non-naturally occurring. Polypeptides and proteins of the disclosure may contain modified, artificial, or synthetic amino acids that do not naturally occur, rendering the entire amino acid sequence non-naturally occurring.

[0320] As used throughout the disclosure, “sequence identity” may be determined by using the stand-alone executable BLAST engine program for blasting two sequences (bl2seq), which can be retrieved from the National Center for Biotechnology Information (NCBI) ftp site, using thedefault parameters (Tatusova and Madden, FEMS Microbiol Lett., 1999, 174, 247-250; which is incorporated herein by reference in its entirety). The terms "identical" or "identity" when used in the context of two or more nucleic acids or polypeptide sequences, refer to a specified percentage of residues that are the same over a specified region of each of the sequences. The percentage can be calculated by optimally aligning the two sequences, comparing the two sequences over the specified region, determining the number of positions at which the identical residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the specified region, and multiplying the result by 100 to yield the percentage of sequence identity. In cases where the two sequences are of different lengths or the alignment produces one or more staggered ends and the specified region of comparison includes only a single sequence, the residues of a single sequence are included in the denominator but not the numerator of the calculation. When comparing DNA and RNA, thymine (T) and uracil (U) can be considered equivalent. Identity can be performed manually or by using a computer sequence algorithm such as BLAST or BLAST 2.0.

[0321] As used throughout the disclosure, the term "endogenous" refers to nucleic acid or protein sequences naturally associated with a target gene or a host cell into which it is introduced.

[0322] As used throughout the disclosure, the term "exogenous" refers to nucleic acid or protein sequences not naturally associated with a target gene or a host cell into which it is introduced, including non-naturally occurring multiple copies of a naturally occurring nucleic acid, e.g., DNA sequence, or naturally occurring nucleic acid sequence located in a non- naturally occurring genome location.

[0323] The disclosure provides methods of introducing a polynucleotide construct comprising a DNA sequence into a host cell. By "introducing" is intended to present to the cell the polynucleotide construct in such a manner that the construct gains access to the interior of the host cell. The methods of the disclosure do not depend on a particular method for introducing a polynucleotide construct into a host cell, only that the polynucleotide construct gains access to the interior of one cell of the host. Methods for introducing polynucleotide constructs into bacteria, plants, fungi and animals are known in the art including, but not limited to, stable transformation methods, transient transformation methods, and virus-mediated methods.
