Caspase-8 (CASP8) is a member of the cysteine aspartate-specific proteases family. It is produced in the cell as procaspase-8, a sluggish zymogen. Procaspase-8 has a long prodomain, carrying two major protein interaction domains, DED1 and DED2, followed by one large (p18) and one small (p10) catalytic subunit. CASP8 is mapped to human chromosome 2q33.
Immunogen
The antiserum was produced against synthesized peptide derived from human Caspase 8 around the phosphorylation site of Tyr380.
Immunogen Range: 346-395
Biochem/physiol Actions
Caspase-8 (CASP8) is involved in apoptosis, inflammation and cellular differentiation. It activates programmed cell death, after death receptor ligation. Casp8 is essential for the clonal expansion of T and B cell. It also participates in lymphocyte homeostasis.

Caspase-8 is an apical caspase which initiates programmed cell death following death receptor ligation. This central role in apoptosis has prompted significant clinical interest in regulating caspase-8 expression and proteolytic activity. However, caspase-8 has also been found to play a
