Rabbit anti Human caspase-8 antibody
recognizes an epitope within the c-terminal region (CT) of caspase-8, otherwise known as Fas-linked ICE-like protease (FLICE), which shares homology with both Fas-associated via death domain (FADD) and the ICE/Ced-3 family of cysteine proteases.
Caspase-8 is classified as an initiator caspase and acts as the most upstream trigger of Fas-Receptor (CD95) and tumour necrosis factor receptor 1 (TNFR1) mediated apoptosis. Upon activation, the cell death receptor Fas, links with the adaptor molecule FADD via corresponding death domains (DD). FADD in turn then binds via death effector domains (DEDs) to procaspase-8, which then undergoes oligomerization and autocatalytic activation.
Active Caspase-8 is capable of cleaving all other known caspases, and also cleaves the Bcl-2 family member BH3-interacting domain death agonist (BID), along with the Bcl-2 associated protein p28Bap31 (Wolf & Green 1999
