Caspase-8 Antibody [3B10]

Procaspase-8 belongs to the family of caspases. Binding of FasL to Fas leads to formation of a receptor complex at the cellular membrane, which was named DISC. The DISC consists of oligomerized receptors, the DD-containing adaptor molecule FADD, procaspase-8, procaspase-10 and c-FLIP. The DISC structure provides a platform for the oligomerization of procaspase-8 that allows two procaspase-8 homodimers to be in the close proximity leading to the initial activation of procaspase-8. At the first cleavage step, the N-terminal p43/p41 and the C-terminal p30 cleavage products are generated. Importantly, these cleavage products already possess catalytic activity. At the second cleavage step, p43/p41 and p30 are processed to p10 and p20, respectively, which leads to the generation of the active caspase-8 heterotetramer (p20/p10) 2.

Recognizes the p20 subunit of mouse caspase-8. Detects bands of ~55kDa (full-length caspase-8) and ~18kDa (apoptosis-induced cleavage fragment) by Western blot. Does not cross-react with human caspase-8.
