ENZYME entry: EC 3.4.21.108

Accepted Name
HtrA2 peptidase
Alternative Name(s)
high temperature requirement protein A2
HtrA2 protease
Omi stress-regulated endoprotease
serine proteinase OMI
Reaction catalysed
Cleavage of non-polar aliphatic amino-acids at the P1 position, with a preference for Val, Ile and Met. At the P2 and P3 positions, Arg is selected most strongly with a secondary preference for other hydrophilic residues
Comment(s)
  • Up-regulated in mammalian cells in response to stress induced by both heat shock and tunicamycin treatment.
  • Can induce apoptosis in a caspase-independent manner through its peptidase activity and in a caspase-dependent manner by disrupting the interaction between caspase and the inhibitor of apoptosis (IAP).
  • Belongs to peptidase family S1B.
