摘 要:错配修复(mismatch repair system, MMR)系统维护着遗传物质的稳定性。错配识别蛋白MutS是错配修复系统行使修复功能的第一个蛋白,具有识别并结合错配的能力。MutS蛋白具有特异性结合错配的特殊功能,在检测突变和SNP的研究中具有很大的应用潜力。近年来已有一些报道介绍了Muts蛋白的一些方法,虽然这些方法还有待改进,但MutS应用前景仍然十分诱人。

Abstract: Mismatch repair system plays a crucial role in the genetic stability of DNA. DNA mismatch binding protein MutS, is the first protein which initiate the function of MMR. MutS has the ability to recognize and binding mismatched base pair. Thus, MutS seems to be a promising tool to detect mutations and SNPs. There were some researches these years to develop techniques, using MutS as a tool to detect mutations and SNPs. These techniques still have deficiencies and more new ideas should be taken to develop these promising techniques.
Key words: mismatch repair; mismatch binding; MutS mutation; SNP
