Structural highlights
FunctionCASP9_HUMAN Involved in the activation cascade of caspases responsible for apoptosis execution. Binding of caspase-9 to Apaf-1 leads to activation of the protease which then cleaves and activates caspase-3. Promotes DNA damage-induced apoptosis in a ABL1/c-Abl-dependent manner. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP).[1] Isoform 2 lacks activity is an dominant-negative inhibitor of caspase-9.[2] References
