FunFam 31: Caspase 1, isoform CRA_b

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Caspase-1. [EC: 3.4.22.36]
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.
