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. |
