PMS2 also known as Postmeiotic Segregation Increased 2 or PMS2 MutL homolog is a protein that participates in DNA mismatch repair. It weighs approximately 96 kDa and often identifies as a member of the MutL protein family. PMS2 is ubiquitously expressed in the body with higher abundances in tissues that undergo rapid proliferation or possess a high mitotic index.
Biological function summary

PMS2 operates as part of the DNA mismatch repair (MMR) complex. It collaborates with other MutL homologs including MLH1 to form a heterodimer which is essential for repairing DNA replication errors. It safeguards genomic integrity and prevents mutations from accumulating in dividing cells serving important functions in cellular viability and genetic stability.

Pathways

PMS2 is involved in the DNA damage response and cell cycle regulation. The protein plays a vital role in the mismatch repair (MMR) pathway. PMS2 partners primarily with MLH1 within this pathway and both proteins work in conjunction to recognize and initiate repair on erroneous DNA sequences that emerge during replication preventing illegitimate recombination and chromosomal rearrangements.

PMS2 mutations occur frequently in Lynch syndrome an inherited cancer predisposition disorder and Turcot syndrome a condition associated with colorectal cancer and brain tumors. MLH1 frequently associates with PMS2 in these disorders as defects in either protein can impair mismatch repair leading to an increased risk of cancer.

General info

Function

Component of the post-replicative DNA mismatch repair system (MMR) (PubMed : 30653781, PubMed : 35189042). 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. Assembly of the MutL-MutS-heteroduplex ternary complex in presence of RFC and PCNA is sufficient to activate endonuclease activity of PMS2. It introduces single-strand breaks near the mismatch and thus generates new entry points for the exonuclease EXO1 to degrade the strand containing the mismatch. DNA methylation would prevent cleavage and therefore assure that only the newly mutated DNA strand is going to be corrected. MutL alpha (MLH1-PMS2) interacts physically with the clamp loader subunits of DNA polymerase III, suggesting that it may play a role to recruit the DNA polymerase III to the site of the MMR. Also implicated in DNA damage signaling, a process which induces cell cycle arrest and can lead to apoptosis in case of major DNA damages. Possesses an ATPase activity, but in the absence of gross structural changes, ATP hydrolysis may not be necessary for proficient mismatch repair (PubMed : 35189042).
