[https://www.uniprot.org/uniprot/CASP1_HUMAN CASP1_HUMAN] Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.<ref>PMID:7876192</ref> <ref>PMID:15498465</ref>
