[MutL Homolog 1 (MLH1), a 84-kD protein encoded by the MLH1 gene, is part of the multi-subunit BASC complex, which may sense abnormal DNA structures and regulate post-replication repair and mismatch repair. Heterodimeric MLH1 Protein and PMS2 provide repair proficiency on heteroduplex DNAs, as well as insertion/deletion mispairs. MLH1 and MLH3 also heterodimerize. Widely expressed, several alternative splice variants occur in diverse tissue types. Some variants lack exons 6/9, 9, 9/10, 9/10/11, 10/11, 12, 16, or 17. Associated with colon, endometrial, and stomach cancers, the defects in MLH1 are a cause of hereditary non-polyposis colorectal cancer. (NCI) ( NCI )]
