Gene name MutL homolog 1
Gene symbol MLH1
Synonyms (NCBI Gene)
COCA2FCC2HNPCCHNPCC2LYNCH2MLH-1MMRCS1hMLH1
Chromosome 3
Chromosome location 3p22.2
Summary The protein encoded by this gene can heterodimerize with mismatch repair endonuclease PMS2 to form MutL alpha, part of the DNA mismatch repair system. When MutL alpha is bound by MutS beta and some accessory proteins, the PMS2 subunit of MutL alpha introd

Protein name DNA mismatch repair protein Mlh1 (MutL protein homolog 1)
Protein 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 recrui
