Alternative Name Caspase-8
Background Caspase-8 (FLICE/MACH-1) is a 55 kDa cytosolic protein with homology to the CD95/Fas-associated signal transducer, FADD/MORT-1, as well as to other caspase (ICE/Ced-3) cysteine proteases. The N-terminal region of caspase-8 contains an amino acid sequence, termed the death domain, that facilitates caspase-8-FADD direct interaction. FADD therefore acts as an adapter molecule, allowing caspase-8 to become recruited to the cytoplasmic region of Fas following receptor activation. Viral proteins (v-FLIPS) which inhibit recruitment and activation of caspase-8 have been isolated. Caspase-8 is produced as a proenzyme (55/50 kDa doublet) which upon receptor aggregation is proteolytically cleaved into smaller subunits of 40/36 (doublet), and 23 kDa. Overexpression of caspase-8 is sufficient to induce apoptosis in certain cell lines (e.g., MCF-7) and this phenotype is blocked by overexpression of the caspase-3 protease inhibitor, CrmA. The antibody recognizes both the proform of human caspase-8 (55/50 kDa doublet) as well as the cleaved form (40/36 kDa doublet) on SDS/PAGE. Full-length recombinant human caspase-8 protein was used as immunogen.
Synonyms: FLICE, MACH-1, Mch5
Molecular Weight 55/50 kDa
Research Area Apoptosis/Necrosis
Application Notes Applications include western blot analysis (1 - 2 µg/ml). Jurkat T cells (ATCC CRL-1573) are suggested as positive controls. Antibodies-online offers several caspase-8 antibodies. A Jurkat model cell system was used to evaluate these antibodies, these results are summarized in the following table. However, actual bands observed could vary according to the cell model system or treatment used.
