C PF00653 BIR Inhibitor of Apoptosis domain Domain BIR stands for 'Baculovirus Inhibitor of apoptosis protein Repeat'. 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]. PFAM PF00653
A PF09057 Smac_DIABLO Second Mitochondria-derived Activator of Caspases Domain Second Mitochondria-derived Activator of Caspases promotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway, and by opposing the inhibitory activity of inhibitor of apoptosis proteins (XIAP-BIR3). The protein assumes an elongated three-helix bundle structure, and forms a dimer in solution [1]. PFAM PF09057
