What is the function of this protein?
Acts as the sensor component of the NLRP6 inflammasome, which mediates inflammasome activation in response to various pathogen-associated signals, leading to maturation and secretion of IL1B and IL18 (PubMed:21593405, PubMed:30392956, PubMed:32424362, PubMed:34678144).  Inflammasomes are supramolecular complexes that assemble in the cytosol in response to pathogens and other damage-associated signals and play critical roles in innate immunity and inflammation (PubMed:30392956).  Acts as a recognition receptor (PRR): recognizes and binds specific pathogens and other damage-associated signals, such as lipoteichoic acid (LTA), a cell-wall component of Gram-positive bacteria, or double stranded RNA (dsRNA) (PubMed:26494172, PubMed:30392956, PubMed:34678144).  May also recognize and bind lipopolysaccharide (LPS), a major component of the outer membrane of Gram-negative bacteria; however, LPS is probably not a major activator of the NLRP6 inflammasome (PubMed:34678144).  Following LTA- or dsRNA-binding, NLRP6 undergoes liquid-liquid phase separation (LLPS), enhancing multivalent interactions, an essential step for the formation of the NLRP6 inflammasome polymeric complex (PubMed:34678144).  The NLRP6 inflammasome acts by promoting recruitment of effector pro-inflammatory caspases (CASP1 and/or CASP4) that catalyze maturation and secretion of IL1B and IL18 in the extracellular milieu (PubMed:30392956).  The NLRP6 inflammasome plays a central role in the maintenance of epithelial integrity and host defense against microbial infections in the intestine (PubMed:21565393, PubMed:22763455, PubMed:23696660, PubMed:26638072, PubMed:28445725, PubMed:30392956).  Required to restrict infection against Gram-positive bacteria by recognizing lipoteichoic acid (LTA), leading to recruitment of CASP4 and CASP1, and subsequent maturation and secretion of IL1B and IL18 (PubMed:30392956).  Involved in intestinal antiviral innate immunity together with DHX15: recognizes and binds viral dsRNA to restrict infection by enteric viruses through the interferon pathway and GSDMD-dependent release of IL18 (PubMed:26494172, PubMed:34678144).  Required to prevent infection by the apicomplexan parasite C. tyzzeri in enterocytes by promoting GSDMD-dependent release of IL18 (PubMed:33372132).  The NLRP6 inflammasome may also regulate the gut microbiota composition by acting as a sensor of microbiota-associated metabolites to form a PYCARD/ASC-dependent inflammasome for downstream IL18 release and secretion of antimicrobial peptides (PubMed:21565393, PubMed:22763455, PubMed:26638072, PubMed:33617596).  Its role in the regulation of the gut microbiota composition is however subject to discussion (PubMed:29281815, PubMed:29281837, PubMed:28801232).  Essential for gut mucosal self-renewal and proliferation (PubMed:21593405, PubMed:21543645, PubMed:21565393).  Regulate mucus secretion in an inflammasome- and autophagy-dependent manner to prevent invasion by enteric bacteria (PubMed:24581500, PubMed:27339979).  During systemic bacterial infections, the NLRP6 inflammasome negatively regulates neutrophil recruitment and neutrophil extracellular traps (NETs) formation (PubMed:22763455, PubMed:30248149, PubMed:33918100, PubMed:33230225).  May promote peripheral nerve recovery following injury via an inflammasome-independent mechanism (PubMed:26253422).
