Entry
EC 3.4.21.108               Enzyme                                 

Name
HtrA2 peptidase;
high temperature requirement protein A2;
HtrA2;
Omi stress-regulated endoprotease;
serine proteinase OMI;
HtrA2 protease;
OMI/HtrA2 protease;
HtrA2/Omi;
Omi/HtrA2
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Serine endopeptidases
BRITE hierarchy
Reaction(IUBMB)
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
This enzyme is upregulated in mammalian cells in response to stress induced by both heat shock and tunicamycin treatment [4]. It 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) [3]. Belongs in peptidase family S1C.
