Function

Serine protease that shows proteolytic activity against a non-specific substrate beta-casein. Promotes or induces cell death either by direct binding to and inhibition of BIRC proteins (also called inhibitor of apoptosis proteins, IAPs), leading to an increase in caspase activity, or by a BIRC inhibition-independent, caspase-independent and serine protease activity-dependent mechanism. Cleaves THAP5 and promotes its degradation during apoptosis. Isoform 2 seems to be proteolytically inactive.

Summary

HtrA2 (Omi) is a serine protease that plays a significant role in apoptosis. Localized to the intermembrane space of the mitochondria, HtrA2 exists as at least four isoforms (1). In response to cellular stress signals, HtrA2 is released into the cytosol. HtrA2 induces cell death either by direct binding to BIRC proteins (also called inhibitor of apoptosis proteins, IAPs), leading to an increase in caspase activity, or by a BIRC-inhibition-independent caspase-independent and Serine protease activity-dependent mechanism (2,3).
