Two of those, MLH1 and MSH2, are further the most common susceptibility genes for hereditary non-polyposis colorectal cancer (HNPCC), while MSH3 and PMS2 are seldom (PMS2) or n … 2019-06-27 · The In silico prediction of the effect of this mutation on (MSH2·MSH6 heterodimer), crucial for MMR complex function [21, 24], revealed that its pathogenicity affects allosteric interactions between different regions within the heterodimer; loss of MSH2 ATPase Domain (loss of nuclear translocation capacity), loss of interaction with EXO1 and Loss of DNA–protein interaction. Summaries for MSH2 gene (According to Entrez Gene, GeneCards, Tocris Bioscience, Wikipedia's Gene Wiki, PharmGKB, UniProtKB/Swiss-Prot, and/or UniProtKB/TrEMBL) About This Section The MSH2 gene product forms two different heterodimers (MSH2-MSH6) and (MSH2-MSH3) which bind to DNA mismatches thereby initiating DNA repair in eurokaryotic cells. Loss of MSH2 function due to mutations causes defective DNA mismatch repair, leading to accumulation of errors in the DNA sequence as cells continue to divide, thereby increasing the risk of tumor formation. MSH2 and Rad17 are required for the activation of the S-phase checkpoint to suppress DNA synthesis in response to MNNG. Thus, MSH2 and ATR function upstream to regulate two branches of the response pathway to DNA damage caused by MNNG.

TK6 and MT1 cells (provided by P. 2003-02-13 2004-01-15 Function: MSH2 can bind to MSH6 or to MSH3 to form the MutS alpha or the MutS beta complexes respectively. While MutS alpha complex binds to base-base and insertion-deletion mismatches, MutS beta only binds to insertion-deletion mismatches.

Heterodimerizes with MLH1 to form MutL alpha. DNA repair is initiated by MutS alpha (MSH2-MSH6) or MutS beta (MSH2-MSH3) binding to a dsDNA mismatch, then MutL alpha is recruited to the heteroduplex.

The MSH2 gene encodes a protein that plays a role in DNA repair. It helps fix mistakes that occur during DNA replication. Mutations of this gene can lead to higher risk for cancer (R). 0 users want this gene increased, 0 users want it decreased 2021-04-10 · Massively parallel functional testing of MSH2 missense variants conferring Lynch syndrome risk. MSH6/2 and PD-L1 Expressions Are Associated with Tumor Growth and Invasiveness in Silent Pituitary Adenoma Subtypes. DNA mismatch repair protein, MutS Homolog 3 (MSH3) is a human homologue of the bacterial mismatch repair protein MutS that participates in the mismatch repair (MMR) system. MSH3 typically forms the heterodimer MutSβ with MSH2 in order to correct long insertion/deletion loops and base-base mispairs in microsatellites during DNA synthesis.

Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and enzyme binding. MSH2 Gln681Glu was not observed at a significant allele frequency in large population cohorts (Lek 2016).
