CPP32 encodes a member of the cysteine-aspartic acid protease (caspase) family that plays a key role in apoptosis. Caspase 3 (also known as CPP32, Apopain, Yama, and PARP cleavage protease) is the most extensively studied apoptotic protein among caspase family members (1-2). Caspase 3 is synthesized as an inactive proenzyme that is processed in cells undergoing apoptosis by self-proteolysis and/or cleavage by other upstream proteases (e.g. Caspases 8, 9 and 10). Alternative splicing of CPP32 results in two transcript variants which encode the same protein. The processed form of Caspase 3 consists of large (theoretical molecular weight 17kD) and small (theoretical molecular weight 12kD) subunits which associate to form an active enzyme. Caspase 3 is cleaved at Asp28/Ser29 and Asp175/Ser176. The active Caspase 3 proteolytically cleaves and activates other caspases (e.g. Caspases 6, 7 and 9), as well as relevant targets in the cells (e.g. PARP and DFF). Variations in levels of Caspase 3 have been reported in cells of short-lived nature and those with a longer life cycle. Caspase 3 is the predominant caspase involved in the cleavage of amyloid beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease (3).
