apoptosome

apoptosome
apop·to·some (ə-popґtə-sōm) [apoptosis + -some] a complex of apoptotic protease activating factor 1 (Apaf-1), caspase 9, cytochrome c>, and other proteins; it is formed when deoxyadenosine triphosphate (dATP) and cytochrome c (released from mitochondria) bind to the C-terminal of and activate Apaf-1, which in turn binds and activates caspase 9. Caspase 9 activates caspase 3 and initiates a cascade that results in apoptosis.
