BINARY GENE EXPRESSION SYSTEM

摘要

The present invention addresses the problem of developing and providing a novel gene expression system with which it is possible to improve the expression efficiency of a gene of interest and to individually control the expression of multiple introduced genes of interest in a desired timeframe and/or tissue, the gene expression system also having low cytotoxicity for the host. Provided is a binary gene expression system comprising: a first expression unit that includes a promoter, a TAL region, and a transcription activity region; and a second expression unit that includes a TAL recognition sequence and a gene of interest or fragment thereof placed under the control of the TAL recognition sequence.
