motifs/domains
  • region of homology with other MutS or MutL homologs, comprising a region of 150 aminoacids
  • a putative helix-turn-helix domain associated with an adenine nucleotide and magnesium binding site
  • mono polymer heteromer , dimer
    HOMOLOGY
    interspecies homolog to yeast mutator gene (bacterial mutL)

    tumoral       loss of function
    in colon and uterus tumor
    tumoral germinal mutation      
    in the 3'-untranslated region (3'-UTR) leads to DNA mismatch repair deficiency, conferring leukemia relapse

    by promoter methylation, associated with poor prognosis in non-small cell lung carcinoma
    Susceptibility
  • to inflammatory bowel disease (Crohn, ulcerative colitis)
  • to prostate cancer
  • Variant & Polymorphism other
  • a protective role for the codon 384 variant allele against prostate cancer
  • rare genetic variants that confer a high risk of prostate cancer when mutated
  • Candidate gene
