摘要: 成簇的规律间隔短回文重复序列及其相关蛋白(clustered regularly interspaced short palindromic repeats–CRISPR-associated proteins, CRISPR-Cas)系统是在结核分枝杆菌中发现的一种新型获得性免疫系统。近年来,在调控结核毒力基因表达、基因定向编辑以及基因组进化方面表现出显著作用。主要从III-A型结核CRISPR-Cas系统的作用机制、改造后的II型CRISPR-Cas系统在结核中的应用以及cas基因的研究进展三方面进行综述,为研究结核发病机制提供理论基础。

Abstract: CRISPR-Cas (the clustered regularly interspaced short palindromic repeats-CRISPR-associated proteins) system acts as an adaptive immune system protects prokaryotes from viruses and plasmids that represented in mycobacterium tuberculosis. And there is evidence that CRISPR-Cas system modulates other processes-the genetic regulation of virulence and genome evolution. At the same time, modified CRISPR-Cas system constitutes a powerful tool for genetic engineering. CRISPR-Cas system shows unprecedented complexity and diversity. In this review, introduction the mechanism, application of genome engineering and recent progress in cas genes of type III-A CRISPR-Cas system are summarized for providing a theoretical basis for the study of mycobacterium tuberculosis.

Key words: mycobacterium tuberculosis, type III-A CRISPR-Cas system, gene editing technology, cas genes
