    PROTEIN
    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • a region of homology with other MutS or MutL homologs, comprising a region of 150 aminoacids encompassing
  • a putative helix-turn-helix domain associated with an adenine nucleotide and magnesium binding sites
  • mono polymer heteromer , dimer
    HOMOLOGY
    interspecies homolog to yeast mutator gene (bacterial mutL)
    Homologene
    FAMILY
  • DNA mismatch repair mutL/hexB family
  • CATEGORY DNA associated
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus
    basic FUNCTION
  • correctin of base-base mismatches and insertion-deletion loops resulting from DNA replication and recombination events
  • possessing an intrinsic low-level ATPase actvity
  • play a far more important role in Lynch syndrome than initially thought
  • its endonuclease activity has distinct biological functions and is essential for genome maintenance and tumor suppression
  • endonuclease function of PMS2 does not play an essential role in meiosis, but it is possible that the protein also contributes to checkpoint-signaling pathways during premeiotic S-phase and spermatogenesis
