Background

HtrA2 (Omi) is a serine protease that plays a significant role in programmed cell death, or apoptosis. Localized to the intermembrane space of the mitochondria, HtrA2 exists predominantly as two isoforms (1). In response to cellular stress signals, HtrA2 is released into the cytosol. One way that HtrA2 induces apoptosis is by binding to BIRC proteins (also called inhibitor of apoptosis proteins, IAPs), and thereby inhibiting their caspase-inhibitory activity (2,3).
