Functioni

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 (By similarity). Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, controls antiviral immunity through the cleavage of CGAS, rendering it inactive (PubMed:28314590).By similarity1 Publication

Catalytic activityi

Strict requirement for an Asp residue at position P1 and has a preferred cleavage sequence of Tyr-Val-Ala-Asp-|-.

Disruption phenotypei

Mutants are resitant to vaccinia virus (VACV) but not vesicular somatitis virus (VSV) infection. They show lower viral loads in the lungs compared to wild type mice, they produce higher levels of type I IFN, IL6 and RSAD2/Viperin after VCAV INFECTION.1 Publication

Interactioni

Subunit structurei

Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (p20) and a 10 kDa (p10) subunit. The p20 subunit can also form a heterodimer with the epsilon isoform which then has an inhibitory effect. May be a component of the inflammasome, a protein complex which also includes PYCARD, CARD8 and NALP2 and whose function would be the activation of proinflammatory caspases. Both the p20 and p10 subunits interact with MEFV (By similarity). Interacts with CARD17/INCA and CARD18 (By similarity).By similarity
