caspase-1 M-CSA #718 | Caspases are thiol endopeptidases that cleave specific proteins after Asp residues and drive apoptosis or inflammation. Caspase-1 is part of the family of inflammatory-caspases, which also includes caspase-4 and caspase-5 in humans and caspase-11, -12, -13 and -14 in mice. Activation of caspase-1 requires oligomerisation of inactive monomeric proenzyme forms. Caspase-1 has a recognition site of Tyr-Val-Ala-Asp-|-. Caspase-1 is also known as interleukin converting enzyme (ICE) and cleaves precursors of the inflammatory interleukin1β and interleukin18 which converts them into mature, active peptides which can initiate a proinflammatory pathway. These often contribute to the pathophysioiogy of many inflammatory and autoimmune diseases, including septic shock, rheumatoid arthritis, and insulin-dependent diabetes mellitus. | Defined by 5 residues: HIS:A-118 [auth A-237]GLY:A-119 [auth A-238]ALA:A-166 [auth A-285]ARG:A-167 [auth A-286]GLU:B-74 [auth B-390] | EC: 3.4.22.36 (PDB Primary Data) |
