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. Plays a key role in cell immunity
CC as an inflammatory response initiator: once activated through formation
CC of an inflammasome complex, it initiates a pro-inflammatory response
CC through the cleavage of the two inflammatory cytokines IL1B and IL18,
CC releasing the mature cytokines which are involved in a variety of
CC inflammatory processes. Cleaves a tetrapeptide after an Asp residue at
CC position P1. Also initiates pyroptosis, a programmed lytic cell death
CC pathway, through cleavage of GSDMD. In contrast to cleavage of
CC interleukins IL1B and IL1B, recognition and cleavage of GSDMD is not
CC strictly dependent on the consensus cleavage site but depends on an
CC exosite interface on CASP1 that recognizes and binds the Gasdermin-D,
CC C-terminal (GSDMD-CT) part. Upon inflammasome activation, during DNA
CC virus infection but not RNA virus challenge, controls antiviral
CC immunity through the cleavage of CGAS, rendering it inactive. In
CC apoptotic cells, cleaves SPHK2 which is released from cells and remains
CC enzymatically active extracellularly. {ECO:0000250|UniProtKB:P29466}.
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:0000250|UniProtKB:P29466};
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. May be a component of the
CC inflammasome, a protein complex which also includes PYCARD, CARD8 and
CC NLRP2 and whose function would be the activation of pro-inflammatory
CC caspases. Component of the AIM2 PANoptosome complex, a multiprotein
CC complex that drives inflammatory cell death (PANoptosis). Both the p10
CC and p20 subunits interact with MEFV. Interacts with CARD17/INCA and
CC CARD18. Interacts with SERPINB1; this interaction regulates CASP1
CC activity. {ECO:0000250|UniProtKB:P29452, ECO:0000250|UniProtKB:P29466}.
CC -!- SUBUNIT: [Caspase-1 subunit p20]: Heterotetramer that consists of two
CC anti-parallel arranged heterodimers, each one formed by a 20 kDa
CC (Caspase-1 subunit p20) and a 10 kDa (Caspase-1 subunit p10) subunit.
CC {ECO:0000250|UniProtKB:P29466}.
CC -!- SUBUNIT: [Caspase-1 subunit p10]: Heterotetramer that consists of two
CC anti-parallel arranged heterodimers, each one formed by a 20 kDa
CC (Caspase-1 subunit p20) and a 10 kDa (Caspase-1 subunit p10) subunit.
CC {ECO:0000250|UniProtKB:P29466}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P29466}. Cell
CC membrane {ECO:0000250|UniProtKB:P29466}.
CC -!- PTM: The two subunits are derived from the precursor sequence by an
CC autocatalytic mechanism. {ECO:0000250|UniProtKB:P29466}.
CC -!- PTM: Ubiquitinated via 'Lys-11'-linked polyubiquitination.
CC Deubiquitinated by USP8. {ECO:0000250|UniProtKB:P29466}.
CC -!- SIMILARITY: Belongs to the peptidase C14A family. {ECO:0000305}.
