Regulates progammed cell death; necessary for normal brain development. Participates with caspase-9 (Apaf-3) in the cytochrome c-dependent activation of caspase-3, leading to apoptosis. This activation requires ATP.
Specificity
Natural and recombinant Rat Apoptotic protease-activating factor 1
Monomer. Oligomerizes upon binding of cytochrome c and dATP. Oligomeric Apaf-1 and pro-caspase-9 bind to each other via their respective NH2-terminal CARD domains. Interacts with UACA. Interacts with APIP.
