| 产品介绍 |
Component of the post-replicative DNA mismatch repair system (MMR). Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. When bound, heterodimers bend the DNA helix and shields approximately 20 base pairs. MutS alpha recognizes single base mismatches and dinucleotide insertion-deletion loops (IDL) in the DNA. MutS beta recognizes larger insertion-deletion loops up to 13 nucleotides long. After mismatch binding, MutS alpha or beta forms a ternary complex with the MutL alpha heterodimer, which is thought to be responsible for directing the downstream MMR events, including strand discrimination, excision, and resynthesis. ATP binding and hydrolysis play a pivotal role in mismatch repair functions. The ATPase activity associated with MutS alpha regulates binding similar to a molecular switch: mismatched DNA provokes ADP-->ATP exchange, resulting in a discernible conformational transition that converts MutS alpha into a sliding clamp capable of hydrolysis-independent diffusion along the DNA backbone. This transition is crucial for mismatch repair. MutS alpha may also play a role in DNA homologous recombination repair. In melanocytes may modulate both UV-B-induced cell cycle regulation and apoptosis. MSH2是核苷酸错配修复酶之一，其突变和多种肿瘤的发生有关，主要用于：先天性结肠癌、散发性结肠癌及一些消化系统肿瘤方面的研究。DNA错配修复系统是指由特异修复DNA碱基错配的酶组成，保证DNA遗传物质的高保真性。它由MLH1、MSH2、PMS1、PMS2、MSH6和MSH3基因组成。如果上述基因发生突变或失活，会使细胞错配修复功能缺陷，产生遗传不稳定性，导致肿瘤易感。MSH2基因突变发生在散发性结肠癌中。 hMSH-2和hMLH1都与肿瘤的发生有关。 |
