CMH-1, or Caspase 7, is a human gene encoded by CASP7. It may also be known as: Caspase-7; CASP-7; Apoptotic protease Mch-3; ICE-like apoptotic protease 3; ICE-LAP3; LICE2; MCH3; caspase 7, apoptosis-related cysteine peptidase. The encoded protein is an enzyme with an amino acid length of 303 and a mass of 34.3 kDa. Other isoforms may exist. CMH-1 is a member of the Peptidase C14A family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
