Development of Mammalian Genome Modification Technique Using Retrotransposon

摘要

To comprehensively modify genome, it is intended to develop a transposition system of the copy and paste type which has an improved efficiency. This object has been achieved by the finding that an LTR retrotransposon is partly usable in a transposition system. Namely, a technique of efficiently transferring a foreign gene into a cell by using a transposon. More specifically speaking, a complete IPA element and a functional promoter sequence are found out. It is clarified that, without a combination of them, a retrotransposon cannot exert its function.
