Caspase-3

Executioner caspase of apoptosis; cleaves PARP, lamins, and hundreds of substrates → orderly cell dismantling. Activated by intrinsic (cytochrome c → caspase-9) and extrinsic (FasL → caspase-8) pathways; BCL-2 and IAPs suppress caspase-3 to evade apoptosis in cancer.

Also known as: CASP3, CPP32, apopain, executioner caspase, SCA-1, Yama
