Background
Caspase-8 (Cysteine-aspartic acid protease 8/Casp8a; also named MCH5, FLICA and MACH alpha 1) is a 28 kDa member of the peptidase C14A family of enzymes. It is widely expressed and is considered an initiating caspase for the apoptotic cascade. Caspase-8 acts on a wide variety of substrates, including procaspases?3, 4, 6, 7, 9 and 10, c?FLIPL and procaspase-8 itself. Human procaspase?8a is a 54?56 kDa, 479 amino acid (aa) protein. It contains two N?terminal death domains (aa 1?177), followed by a catalytic site that utilizes His317Gly318 plus Cys360. Normally, it is an inactive, cytosolic monomer. But following death?domain (DD) containing receptor oligomerization, Caspase?8 is recruited to the death-inducing signaling complex (DISC) that forms around the death domains of the oligomerized receptor.
