Other names include: Postmeiotic segregation increased 2-like protein 5; Postmeiotic segregation increased protein 7; Putative postmeiotic segregation increased 2 pseudogene 5; Postmeiotic segregation increased protein 4; PMS2L5; postmeiotic segregation increased 2 pseudogene 5. The encoded protein has an amino acid length of 134 and a mass of 15.2 kDa. Other isoforms may exist. PMS7 is a member of the DNA mismatch repair MutL/HexB family.
