This gene encodes a pyrin-like protein containing a pyrin domain, a nucleotide-binding site (NBS) domain, and a leucine-rich repeat (LRR) motif. This protein interacts with the apoptosis-associated speck-like protein PYCARD/ASC, which contains a caspase recruitment domain, and is a member of the NLRP3 inflammasome complex. This complex functions as an upstream activator of NF-kappaB signaling, and it plays a role in the regulation of inflammation, the immune response, and apoptosis. The SARS-CoV 3a protein, a transmembrane pore-forming viroporin, has been shown to activate the NLRP3 inflammasome via the formation of ion channels in macrophages. Mutations in this gene are associated with familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), chronic infantile neurological cutaneous and articular (CINCA) syndrome, neonatal-onset multisystem inflammatory disease (NOMID), keratoendotheliitis fugax hereditarian, and deafness, autosomal dominant 34, with or without inflammation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. Alternative 5' UTR structures are suggested by available data; however, insufficient evidence is available to determine if all of the represented 5' UTR splice patterns are biologically valid.

A study in mice demonstrated that ethanol administration significantly upregulated the mRNA and protein expression of the NLRP3, a key inflammasome component in the NOD-like receptor signaling pathway, which was effectively reversed by astaxanthin supplementation [Liu et al. DOI:10.3390/Md17030181]. A study in human postmortem renal tissue demonstrated that arginine-vasopressin (AVP) expression in tubular epithelial cells and arteriolar walls was significantly more intense in saltwater drowning cases compared to both freshwater drowning and control deaths by gunshot, establishing it as a potential marker for the differential diagnosis of saltwater drowning [Barranco et al. DOI:10.1007/S00414-020-02274-4].
