Serine protease HTRA2 mitochondrial is an enzyme that in humans is encoded by the HTRA2 gene.This gene encodes a serine protease. HtrA2 also known as Omi is a mitochondrially-located serine protease. HtrA2 can be released from the mitochondria during apoptosis and uses its four most N-terminal amino acids to mimic a caspase and be recruited by IAP caspase inhibitors such as XIAP and CIAP1/2.
