Background

Function：Heterodimerizes with PMS2 to form MutL alpha, a component of the post-replicative DNA mismatch repair system (MMR). 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. Heterodimerizes with MLH3 to form MutL gamma which plays a role in meiosis

Isoforms & Post-Translational Modification：P40692 has 3 isomers: P40692-1: 84601 Da (predicted); P40692-2: 58375 Da (predicted); P40692-3: 73837 Da (predicted).
Acetylated (PubMed:30770470). Deacetylated by HDAC6 which prevents the MutL alpha complex, formed by the MLH1-PMS2 heterodimer, from being recruited to the MutS alpha complex, formed by the MSH2-MSH6 heterodimer, leading to tolerance of DNA damage (PubMed:30770470);Ubiquitinated by UBR4; leading to proteasomal degradation. This ubiquitination is counteracted by the deubiquitinase USP5

Subunit：Component of the DNA mismatch repair (MMR) complex composed at least of MSH2, MSH3, MSH6, PMS1 and MLH1 (PubMed:26300262). Heterodimer of MLH1 and PMS2 (MutL alpha), MLH1 and PMS1 (MutL beta) or MLH1 and MLH3 (MutL gamma). Forms a ternary complex with MutS alpha (MSH2-MSH6) or MutS beta (MSH2-MSH3). Part of the BRCA1-associated genome surveillance complex (BASC), which contains BRCA1, MSH2, MSH6, MLH1, ATM, BLM, PMS2 and the RAD50-MRE11-NBS1 protein complex (PubMed:10783165). This association could be a dynamic process changing throughout the cell cycle and within subnuclear domains (PubMed:10097147). Interacts with MCM9; the interaction recruits MLH1 to chromatin (PubMed:26300262). Interacts with MCM8 (PubMed:26300262). Interacts with PMS2; this interaction promotes MLH1 stability (PubMed:11427529, PubMed:22753075, PubMed:39032648). Interacts with MBD4 (PubMed:10097147). Interacts with EXO1 (PubMed:11427529, PubMed:11429708, PubMed:12414623, PubMed:14676842, PubMed:22753075). Interacts with MTMR15/FAN1 (PubMed:20603073)
