Title: Caspase-8
CAS Registry Number: 179241-78-2
Additional Names: FADD-like ICE; FLICE; MACH; MORT1-associated CED-3 homolog; Mch5
Literature References: Initiator caspase required for Fas/CD95/APO-1-mediated apoptosis. Synthesized as a 55 kDa inactive zymogen, procaspase-8. Activated by association with the death-inducing signaling complex (DISC), leading to the release of active ~12 and ~20 kDa subunits into the cytosol.
