First detected in bone marrow promyelocytes. Expression increases throughout myelocyte differentiation and peaks in the mature myelomonocytic cells.
The B box-type zinc finger interacts, possibly intramolecularly, with the pyrin domain; this may be an autoinhibitory mechanism released by PSTPIP1 binding.
Involved in the regulation of innate immunity and the inflammatory response in response to IFNG/IFN-gamma. Organizes autophagic machinery by serving as a platform for the assembly of ULK1, Beclin 1/BECN1, ATG16L1, and ATG8 family members and recognizes specific autophagy targets, thus coordinating target recognition with assembly of the autophagic apparatus and initiation of autophagy. Acts as an autophagy receptor for the degradation of several inflammasome components, including CASP1, NLRP1 and NLRP3, hence preventing excessive IL1B- and IL18-mediated inflammation (PubMed:16785446, PubMed:17431422, PubMed:26347139). However, it can also have a positive effect in the inflammatory pathway, acting as an innate immune sensor that triggers PYCARD/ASC specks formation, caspase-1 activation, and IL1B and IL18 production (PubMed:16037825, PubMed:27030597, PubMed:28835462). It is required for PSTPIP1-induced PYCARD/ASC oligomerization and inflammasome formation. Recruits PSTPIP1 to inflammasomes, and is required for PSTPIP1 oligomerization (PubMed:10807793, PubMed:11468188, PubMed:17964261, PubMed:18577712, PubMed:19109554, PubMed:19584923).
Familial Mediterranean fever, autosomal recessive
ARFMF
A hereditary periodic fever syndrome characterized by recurrent episodic fever, serosal inflammation and pain in the abdomen, chest or joints. It is frequently complicated by reactive amyloidosis, which leads to renal failure and can be prophylactically treated with colchicine.
None
The disease is caused by variants affecting the gene represented in this entry. The disease-associated mutations in the B30.2/SPRY domain perturb ULK1 recruitment and autophagic degradation of inflammasome components, including NLRP3, and hence may contribute to the inflammatory phenotype associated with ARFMF.
Familial Mediterranean fever, autosomal dominant
ADFMF
A hereditary periodic fever syndrome characterized by periodic fever, serosal inflammation and pain in the abdomen, chest or joints as seen also in the autosomal recessive form of the disease. It is associated with reactive renal amyloidosis and characterized by colchicine unresponsiveness.
None
The disease is caused by variants affecting the gene represented in this entry.
Pyrin-associated autoinflammatory disease
PAAND
An autosomal dominant autoinflammatory disorder characterized by childhood onset of recurrent episodes of fever, neutrophilic dermatosis, myalgia and arthralgia. The neutrophilic dermatosis comprises a spectrum of clinical manifestations, including severe acne, sterile skin abscesses, pyoderma gangrenosum, and neutrophilic small-vessel vasculitis. Pathological examination of affected skin shows a dense, predominantly neutrophilic, vascular, perivascular, and interstitial infiltrate. PAAND has incomplete penetrance and variable expressivity.
None
The disease is caused by variants affecting the gene represented in this entry.
Cleaved by CASP1 (Probable). The N-terminal cleavage product localizes to the nucleus as a filamentous network and to the cytoplasm, interacts more strongly with RELA and NFKBIA than the full-length protein, enhances the nuclear localization of RELA and induces NFKBIA proteolysis. The C-terminal cleavage product localizes to the cytoplasm.
Phosphorylation at Ser-242 is required for the interaction with 14-3-3 proteins and down-regulation of pyrin proinflammatory activity.
Expressed in peripheral blood leukocytes, particularly in mature granulocytes and to a lesser extent in monocytes but not in lymphocytes. Detected in spleen, lung and muscle, probably as a result of leukocyte infiltration in these tissues. Not expressed in thymus, prostate, testis, ovary, small intestine, colon, heart, brain, placenta, liver, kidney, pancreas. Expression detected in several myeloid leukemic, colon cancer, and prostate cancer cell lines.
