Function
Functions as a key mediator in apoptosis and inflammation (PubMed:11103777, PubMed:12646168, PubMed:15030775, PubMed:17349957, PubMed:17599095, PubMed:19158675, PubMed:19158676, PubMed:19234215, PubMed:19494289, PubMed:21487011, PubMed:24630722, PubMed:25847972, PubMed:30674671, PubMed:34678144, PubMed:36050480). Promotes caspase-mediated apoptosis involving predominantly caspase-8 and also caspase-9 in a probable cell type-specific manner (PubMed:11103777, PubMed:12646168). Involved in activation of the mitochondrial apoptotic pathway, promotes caspase-8-dependent proteolytic maturation of BID independently of FADD in certain cell types and also mediates mitochondrial translocation of BAX and activates BAX-dependent apoptosis coupled to activation of caspase-9, -2 and -3 (PubMed:14730312, PubMed:16964285). Involved in innate immune response by acting as an integral adapter in the assembly of various inflammasomes (NLRP1, NLRP2, NLRP3, NLRP6, AIM2 and probably IFI16) which recruit and activate caspase-1 leading to processing and secretion of pro-inflammatory cytokines (PubMed:15030775, PubMed:16982856, PubMed:17349957, PubMed:17599095, PubMed:19158675, PubMed:19158676, PubMed:19234215, PubMed:21487011, PubMed:23530044, PubMed:24630722, PubMed:25847972, PubMed:29440442, PubMed:30674671, PubMed:33980849, PubMed:34678144, PubMed:34706239). Caspase-1-dependent inflammation leads to macrophage pyroptosis, a form of cell death (PubMed:24630722). The function as activating adapter in different types of inflammasomes is mediated by the pyrin and CARD domains and their homotypic interactions (PubMed:14499617, PubMed:19234215, PubMed:24630722). Clustered PYCARD nucleates the formation of caspase-1 filaments through the interaction of their respective CARD domains, acting as a platform for of caspase-1 polymerization (PubMed:24630722). In the NLRP1 and NLRC4 inflammasomes seems not be required but facilitates the processing of procaspase-1 (PubMed:17349957). In cooperation with NOD2 involved in an inflammasome activated by bacterial muramyl dipeptide leading to caspase-1 activation (PubMed:16964285). May be involved in RIGI-triggered pro-inflammatory responses and inflammasome activation (PubMed:19915568). In collaboration with AIM2 which detects cytosolic double-stranded DNA may also be involved in a caspase-1-independent cell death that involves caspase-8 (PubMed:19158675, PubMed:19158676). In adaptive immunity may be involved in maturation of dendritic cells to stimulate T-cell immunity and in cytoskeletal rearrangements coupled to chemotaxis and antigen uptake may be involved in post-transcriptional regulation of the guanine nucleotide exchange factor DOCK2; the latter function is proposed to involve the nuclear form (PubMed:22732093). Also involved in transcriptional activation of cytokines and chemokines independent of the inflammasome; this function may involve AP-1, NF-kappa-B, MAPK and caspase-8 signaling pathways (PubMed:12486103, PubMed:16585594). For regulation of NF-kappa-B activating and inhibiting functions have been reported (PubMed:12486103). Modulates NF-kappa-B induction at the level of the IKK complex by inhibiting kinase activity of CHUK and IKBK (PubMed:12486103, PubMed:16585594). Proposed to compete with RIPK2 for association with CASP1 thereby down-regulating CASP1-mediated RIPK2-dependent NF-kappa-B activation and activating interleukin-1 beta processing (PubMed:16585594). Modulates host resistance to DNA virus infection, probably by inducing the cleavage of and inactivating CGAS in presence of cytoplasmic double-stranded DNA (PubMed:28314590); May have a regulating effect on the function as inflammasome adapter; Seems to inhibit inflammasome-mediated maturation of interleukin-1 beta

Subunit
Self-associates; enforced oligomerization induces apoptosis, NF-kappa-B regulation and interleukin-1 beta secretion (PubMed:15641782, PubMed:17599095, PubMed:33420028, PubMed:33420033, PubMed:34706239). Homooligomers can form disk-like particles of approximately 12 nm diameter and approximately 1 nm height (PubMed:15641782, PubMed:17599095). Next to isoform 1, also isoform 2 and isoform 3 may be involved in oligomerization leading to functional regulation (Probable). Component of several inflammasomes containing one pattern recognition receptor/sensor, such as NLRP1, NLRP2, NLRP3, NLRP6, NLRC4, AIM2, MEFV or NOD2, and probably NLRC4, NLRP12 or IFI16 (PubMed:11374873, PubMed:12191486, PubMed:15030775, PubMed:15456791, PubMed:19158676, PubMed:23530044, PubMed:27432880, PubMed:29440442, PubMed:30674671, PubMed:33980849, PubMed:34678144, PubMed:35559676). Major component of the ASC pyroptosome, a 1-2 um supramolecular assembly (one per macrophage cell) which consists of oligomerized PYCARD dimers and CASP1 (PubMed:17599095). Interacts with CASP1 (precursor form); the interaction induces activation of CASP1 leading to the processing of interleukin-1 beta; PYCARD competes with RIPK2 for binding to CASP1 (PubMed:11967258, PubMed:14634131, PubMed:16585594, PubMed:17599095, PubMed:33420033). Interacts with NLRP3; the interaction requires the homooligomerization of NLRP3 (PubMed:11786556, PubMed:15020601, PubMed:15030775, PubMed:34341353, PubMed:35559676). Interacts with NLRP2, NLRC4, MEFV, CARD16, AIM2, IFI16, NOD2, RIGI, RIPK2, PYDC1, PYDC2, NLRP10, CASP8, CHUK, IKBKB and BAX (PubMed:11374873, PubMed:11498534, PubMed:12486103, PubMed:12646168, PubMed:12656673, PubMed:14730312, PubMed:15096476, PubMed:15456791, PubMed:17178784, PubMed:17339483, PubMed:18362139, PubMed:19158675, PubMed:19158676, PubMed:19915568, PubMed:21575908, PubMed:23530044, PubMed:29440442, PubMed:33980849).
