Function

Most upstream protease of the activation cascade of caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death. Binding to the adapter molecule FADD recruits it to either receptor. The resulting aggregate called death- inducing signaling complex (DISC) performs CASP8 proteolytic activation. The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases. Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC. Cleaves and activates CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10. May participate in the GZMB apoptotic pathways. Cleaves ADPRT. Hydrolyzes the small-molecule substrate, Ac-Asp-Glu-Val-Asp-|-AMC. Likely target for the cowpox virus CRMA death inhibitory protein. Isoform 5, isoform 6, isoform 7 and isoform 8 lack the catalytic site and may interfere with the pro-apoptotic activity of the complex.

Summary

Caspase-8 (MACH/FLICE/Mch5) is a member of a family of cysteine-requiring aspartate proteases that participate in the intracellular signaling cascade leading to apoptosis, or programmed cell death (1-4). Caspase-8 is recruited to death-inducing signaling complex (DISC) CD95 (Fas/APO-1) and tumor necrosis factor receptor 1 (TNFR1) and is subsequently activated by proteolytic cleavage into two residues, p10 and p18 (1-4). Active caspase-8, the first in the caspase signaling cascade, signals downstream caspases to eventually induce apoptosis.
