Anti-Caspase-8 Antibody, clone 3B10 clone 3B10, from rat

Caspase-8 (UniProt: O89110; also known as EC: 3.4.22.61, CASP-8, CASP8, MCH5, FLICE, MACH) is encoded by the Casp8 gene (Gene ID: 12370) in murine species. Caspase-8 is a cysteine protease that plays a major role in the extrinsic apoptotic signaling pathway via death receptors. In its inactive form it associates with FADD by interactions between their DED motifs and within the FAS-FADD-Caspase 8 complex caspase 8 undergoes self-cleavage to convert to the active form. Activated caspase 8 is subsequently released to the cytosol and it cleaves downstream effector caspases 3, 4, 6, 7, 9 and 10. Caspase 8 is expressed in wide variety of tissues and its highest expression has been reported in spleen, thymus, lung, liver, and kidney. Low levels of expression are observed in heart, brain, testis, and skeletal muscle. Caspase-8 is produced with propetides (aa 1-218 and 377-387) that are cleaved under appropriate signals to produce a p20 (aa 219-376) and a p10 (aa 388-480) subunit. Active caspase 8 is a heterotetramer that consists of two p20 and two p10 subunits.
