Enzyme Information
| 3.4.22.36 | Caspase-1. based on mapping to UniProt P29466 Strict requirement for an Asp residue at position P1 and has a preferred cleavage sequence of Tyr-Val-Ala-Asp-|-. -!- Part of the family of inflammatory-caspases, which also includes caspase-4 (EC 3.4.22.57) and caspase-5 (EC 3.4.22.58) in humans and caspase-11 (EC 3.4.22.64), caspase-12, caspase-13 and caspase-14 in mice. -!- Contains a caspase-recruitment domain (CARD) in its N-terminal prodomain, which plays a role in procaspase activation. -!- Cleaves pro-interleukin-1-beta (pro-IL-1-beta) to form mature IL-1- beta, a potent mediator of inflammation. -!- Also activates the proinflammatory cytokine, IL-18, which is also known as interferon-gamma-inducing factor. -!- Inhibited by Ac-Tyr-Val-Ala-Asp-CHO. -!- Caspase-11 plays a critical role in the activation of caspase-1 in mice whereas caspase-4 enhances its activation in humans. -!- Belongs to peptidase family C14. |
