摘要
An adeno-associated virus (AAV) vector for inserting a desired nucleic acid into a nucleic acid in a cell, wherein the nucleic acid in the cell comprises a region consisting of a first nucleotide sequence and a region consisting of a second nucleotide sequence in order in a direction from a 5' end to a 3' end, wherein the vector comprises a first gRNA target sequence, a region consisting of a first nucleotide sequence, the desired nucleic acid, a region consisting of a second nucleotide sequence, a second gRNA target sequence, a cell-specific promoter, a sequence encoding a Cas9 nuclease, an RNA polymerase III promoter, a sequence encoding a first gRNA recognizing the first gRNA target sequence and a sequence encoding a second gRNA recognizing the second gRNA target sequence, wherein the vector yields a nucleic acid fragment comprising a region consisting of a first nucleotide sequence, the desired nucleic acid and the region consisting of the second nucleotide sequence by the Cas9 nuclease, wherein a first nucleotide sequence in the nucleic acid in the cell and a first nucleotide sequence in the vector are linked by a microhomology-mediated joining and a second nucleotide sequence in the nucleic acid in the cell and a second nucleotide sequence in the vector are linked by a microhomology-mediated joining, thereby inserting the desired nucleic acid between the region consisting of the first nucleotide sequence and the region consisting of the second nucleotide sequence in the nucleic acid in the cell.
