CC -!- FUNCTION: Thiol protease involved in a variety of inflammatory
CC processes by proteolytically cleaving other proteins, such as the
CC precursors of the inflammatory cytokines interleukin-1 beta (IL1B) and
CC interleukin 18 (IL18) as well as the pyroptosis inducer Gasdermin-D
CC (GSDMD), into active mature peptides (PubMed:21147462,
CC PubMed:32109412). Plays a key role in cell immunity as an inflammatory
CC response initiator: once activated through formation of an inflammasome
CC complex, it initiates a pro-inflammatory response through the cleavage
CC of the two inflammatory cytokines IL1B and IL18, releasing the mature
CC cytokines which are involved in a variety of inflammatory processes
CC (PubMed:21147462). Cleaves a tetrapeptide after an Asp residue at
CC position P1 (PubMed:21147462). Also initiates pyroptosis, a programmed
CC lytic cell death pathway, through cleavage of GSDMD (PubMed:32109412).
CC In contrast to cleavage of interleukins IL1B and IL1B, recognition and
CC cleavage of GSDMD is not strictly dependent on the consensus cleavage
CC site but depends on an exosite interface on CASP1 that recognizes and
CC binds the Gasdermin-D, C-terminal (GSDMD-CT) part (PubMed:32109412).
CC Upon inflammasome activation, during DNA virus infection but not RNA
CC virus challenge, controls antiviral immunity through the cleavage of
CC CGAS, rendering it inactive (PubMed:28314590). In apoptotic cells,
CC cleaves SPHK2 which is released from cells and remains enzymatically
CC active extracellularly (By similarity). {ECO:0000250|UniProtKB:P29466,
CC ECO:0000269|PubMed:21147462, ECO:0000269|PubMed:28314590,
CC ECO:0000269|PubMed:32109412}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Strict requirement for an Asp residue at position P1 and has a
CC preferred cleavage sequence of Tyr-Val-Ala-Asp-|-.; EC=3.4.22.36;
CC Evidence={ECO:0000269|PubMed:21147462};
CC -!- SUBUNIT: Heterotetramer that consists of two anti-parallel arranged
CC heterodimers, each one formed by a 20 kDa (Caspase-1 subunit p20) and a
CC 10 kDa (Caspase-1 subunit p10) subunit (PubMed:32109412). May be a
CC component of the inflammasome, a protein complex which also includes
CC PYCARD, CARD8 and NLRP2 and whose function would be the activation of
CC pro-inflammatory caspases (By similarity). Component of the AIM2
CC PANoptosome complex, a multiprotein complex that drives inflammatory
CC cell death (PANoptosis) (PubMed:34471287). Both the p10 and p20
CC subunits interact with MEFV (By similarity). Interacts with CARD17/INCA
CC and CARD18 (By similarity). Interacts with SERPINB1; this interaction
CC regulates CASP1 activity (By similarity).

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