It is found repeated in inhibitor of apoptosis proteins (IAPs), and in fact it is also known as IAP repeat. These domains characteristically have a number of invariant residues, including 3 conserved cysteines and one conserved histidine that coordinate a zinc ion. They are usually made up of 4-5 alpha helices and a three-stranded beta-sheet. BIR is also found in other proteins known as BIR-domain-containing proteins (BIRPs), such as Survivin (Swiss:O15392) [2].

caspase-9  M-CSA #816

Caspase-9 from Homo sapiens is a cysteine dependent aspartate specific protease. When activated, it will cleave the Caspase-3 peptide bond between Asp 175 and Ser 176. On existence as a monomer, Caspase-9 is inactive, but on dimerizing which is a result of the release of cytochrome c from the mitochondria cleaving procaspase-9 it becomes active, or it can be activated by making a complex with APAF1. It is involved in the process of apoptosis (programmed cell death) which is a central role in the development and homeostasis of an organism and Caspase-9 is linked to the normal development of the central nervous system.
