Abstract:

CRISPR is one of the major research focus of gene editing at present, and has been widely used in research areas like disease treatment and crop improvement. Among these CRIPSR systems, CRISPR-Cas9 system is the most deeply studied one. How to reduce the off-target effect in mammalian cells is one of the major challenges of CRISPR-Cas9. The functional regulation system of CRISPR-Cas9 can be constructed by using light or active molecule induced small molecule reaction tools. By controlling the function of sgRNA, Cas9 or Cas9/sgRNA complex, spatial-temporal regulation of the gene editing function of CRISPR-Cas9 can be achieved, and the probability of non-specific action can be greatly reduced. At the same time, small molecules have little interference with the original system, thus small molecule reactions have becoming more and more important tools for the CRISPR-Cas9 regulation systems. In this review, we summarize the main research progress of CRISPR-Cas9 functional regulation system based on small molecule reaction tools, and prospected the future development of this field.

Key words: Gene editing, CRISPR-Cas9, Off-target effect, Small molecule reaction, Functional regulation system
