Caspase-1 (CASP1) is a thiol protease that cleaves IL-1 beta between Asp and Ala. This cleavage causes the release of the mature cytokine which is involved in a variety of inflammatory processes. CASP1 is important for defense against pathogen. It cleaves and activates sterol regulatory element binding proteins (SREBPs). CASP1 also promotes apoptosis. Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, CASP1 controls antiviral immunity through the cleavage of CGAS and renders it inactive.
