PMS7 (postmeiotic segregation increased protein 7), also known as PMS2P5 (postmeiotic segregation increased 2 pseudogene 5), PMS2L5 (postmeiotic segregation increased 2-like protein 5) or PMS4 (postmeiotic segregation increased protein 4), is a 134 amino acid protein that belongs to the DNA mismatch repair mutL/hexB family. Participating in ATP binding and in mismatched DNA binding, PMS7 is likely a predominant target for regulation by p53. PMS7 is reactive to DNA damage and p53 activation in normal human fibroblasts, and contains p53-response elements within its first intron. PMS7 may function as a sensor in DNA repair mechanisms and may act as a critical determinant for the decision between cell-cycle arrest and apoptosis. The gene that encodes PMS7 maps to human chromosome 7q11.23. |
