HtrA2 peptidase.
based on mapping to UniProt O43464
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.
-!- 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.
