Embodiment Construction

[0080] The principles and features of the present invention will be described below in conjunction with specific drawings, and the examples given are only used to explain the present invention, not to limit the scope of the present invention.

[0081] 1. Screening of the human Tyr gene pathogenic mutation site, confirming that the proline (referred to as Pro) site at position 81 of the human TYR gene is a pseudo-mutation site.

[0082] I albinism is caused by mutations in the TYR gene, and 38 pathogenic mutations were screened using the OMIM online database (as shown in Table 1, a total of 20 are listed). Due to the limited mutation sites included in OMIM, the present invention also utilizes the ExAC database to screen the mutation situation of the human TYR gene, and screens 283 mutation sites altogether (as shown in Table 2 and figure 1 Shown, Table 2 lists 20 kinds of mutations). Then, the ClinVar database was used to search for mutations at TYR pathogenic sites, and a tot...

Abstract

The invention discloses a sgRNA guide sequence specifically targeting mouse Tyr gene and application thereof, belonging to the technical fields of medical genetics and molecular biology. The nucleotide sequence corresponding to the sgRNA is any one of SEQ ID NO.1, SEQ ID NO.2 and SEQ ID NO.3. The present invention also discloses a method for editing the mouse Tyr gene by using the above-mentioned sgRNA guide sequence specifically targeting the mouse Tyr gene. The sgRNA guide sequence of the present invention can mediate the Cas9 protein to efficiently cut target DNA, and then be used to edit the mouse Tyr gene and affect the function of the protein encoded by the mouse Tyr gene. The sgRNA guide sequence of the present invention can realize high-efficiency targeting through the CRISPR / Cas9 system, and the efficiency is 100%.

Description

technical field [0001] The invention relates to a sgRNA guide sequence specifically targeting mouse Tyr gene and application thereof, belonging to the technical fields of medical genetics and molecular biology. Background technique [0002] The CRISPR / Cas system was first discovered in bacteria, and it performs acquired immune functions in eubacteria and archaea, which can resist the invasion of foreign viruses and plasmids. People have modified the CRISPR / Cas system of microorganisms by means of genetic engineering, thereby creating a gene editing targeting system that can be widely used in higher organisms, the CRISPR / Cas9 system. Since the system came out in 2012, it has injected strong impetus into life science and biomedical research, and has become a research hotspot in recent years. Since 2013, researchers have successfully edited the genome in mammalian cells by using the DNA binding activity and endonuclease activity of CRISPR / Cas9. In the CRISPR / Cas9 system, unde...
