特徴

• Caspase-8/FADD-like ICE (FLICE), is an ~55kD cytosolic protein belonging to the Fas/APO-1/CD95 death-inducing signaling complex.  Although researchers have defined eight different isoforms of caspase-8 at the mRNA level (8/a-h), significant expression of only Caspase-8/a and /b occurs at the protein level in a variety of cell lines.
• Caspase-8 contains two death effector domains (DEDs) and exhibits sequence homology to both FADD, a signal transducer of Fas-induced apoptosis, and to the ICE/CED-3 family of cysteine proteases.
• Caspase-8 binds to FADD through its amino terminal DEDs and induces apoptosis when overexpressed.  Activation of Caspase-8 involves a two-step proteolysis whereby the cleavage of Caspase-8 generates a 43kD fragment (p43) and a 12kD fragment further processed to 10kD, then the cleavage of receptor-associated p43 yields p26 and the release of the active site containing p18.  A number of cytosolic factors inhibit the FADD-Caspase-8 containing signaling complex, including the ICE/CED-3 family inhibitor CrmA which inhibits Caspase-8 protease activity, and the short and long forms of FLIP that bind to the FADD-Caspase-8 complex.
