Web18 iun. 2024 · Definition / general. PMS2 is a component of the DNA mismatch repair system. The PMS2 gene (on chromosome 7) encodes an endonuclease that forms a heterodimer with MLH1 to form the MutL alpha complex which is activated upon recognition of DNA mismatches, insertions or deletions by MutS alpha and MutS beta heterodimers. WebIn hereditary adenocarcinomas (Lynch syndrome), germline mutations most commonly involve the MSH2 gene but can also involve the MLH1, MSH6, and PMS2 genes, resulting in loss of nuclear staining of the particular protein (Figs. 14.22 and 14.23). 234,235 Antibodies to MLH1, MSH2, MSH6, and PMS2 proteins can be used to screen for MSI-H neoplasms ...
