Function

May function as an inducer of apoptosis. Interacts selectively with ASC and this complex may function as an upstream activator of NF-kappa-B signaling. Inhibits TNF-alpha induced activation and nuclear translocation of RELA/NF-KB p65. Also inhibits transcriptional activity of RELA. Activates caspase-1 in response to a number of triggers including bacterial or viral infection which leads to processing and release of IL1B and IL18. {ECO:0000269PubMed:11786556, ECO:0000269PubMed:14662828}.

Disease Associations

Familial cold autoinflammatory syndrome 1 (FCAS1) [MIM:120100]: A rare autosomal dominant systemic inflammatory disease characterized by recurrent episodes of maculopapular rash associated with arthralgias, myalgias, fever and chills, swelling of the extremities, and conjunctivitis after generalized exposure to cold. Rarely, some patients may also develop late-onset renal amyloidosis. {ECO:0000269PubMed:11687797, ECO:0000269PubMed:11992256, ECO:0000269PubMed:12355493, ECO:0000269PubMed:12522564, ECO:0000269PubMed:15593220, ECO:0000269PubMed:17284928}. Note=The disease is caused by mutations affecting the gene represented in this entry.Muckle-Wells syndrome (MWS) [MIM:191900]: A hereditary periodic fever syndrome characterized by fever, chronic recurrent urticaria, arthralgias, progressive sensorineural deafness, and reactive renal amyloidosis. The disease may be severe if generalized reactive amyloidosis occurs. {ECO:0000269PubMed:11687797, ECO:0000269PubMed:11992256, ECO:0000269PubMed:12355493, ECO:0000269PubMed:15593220}. Note=The disease is caused by mutations affecting the gene represented in this entry.Chronic infantile neurologic cutaneous and articular syndrome (CINCA) [MIM:607115]: Rare congenital inflammatory disorder characterized by a triad of neonatal onset of cutaneous symptoms, chronic meningitis, and joint manifestations with recurrent fever and inflammation. {ECO:0000269PubMed:12032915, ECO:0000269PubMed:12483741, ECO:0000269PubMed:14630794, ECO:0000269PubMed:15231984, ECO:0000269PubMed:15334500, ECO:0000269PubMed:15593220}.

Tissue Specificity

Expressed in blood leukocytes. Strongly expressed in polymorphonuclear cells and osteoblasts. Undetectable or expressed at a lower magnitude in B- and T-lymphoblasts, respectively. High level of expression detected in chondrocytes. Detected in non-keratinizing epithelia of oropharynx, esophagus and ectocervix and in the urothelial layer of the bladder. {ECO:0000269PubMed:11786556, ECO:0000269PubMed:12032915, ECO:0000269PubMed:17164409, ECO:0000269PubMed:17907925}.
