Function
Sensor component of the NLRP3 inflammasome, which mediates inflammasome activation in response to defects in membrane integrity, leading to secretion of inflammatory cytokines IL1B and IL18 and pyroptosis (PubMed:19362020, PubMed:23582325, PubMed:26642356, PubMed:26814970, PubMed:27374331, PubMed:27929086, PubMed:28656979, PubMed:28847925, PubMed:30518920, PubMed:36178239). In response to pathogens and other damage-associated signals that affect the integrity of membranes, initiates the formation of the inflammasome polymeric complex composed of NLRP3, CASP1 and PYCARD/ASC (PubMed:16407889, PubMed:18403674, PubMed:19362020, PubMed:26642356, PubMed:26814970, PubMed:27374331, PubMed:28847925). Recruitment of pro-caspase-1 (proCASP1) to the NLRP3 inflammasome promotes caspase-1 (CASP1) activation, which subsequently cleaves and activates inflammatory cytokines IL1B and IL18 and gasdermin-D (GSDMD), promoting cytokine secretion and pyroptosis (PubMed:16546100, PubMed:17008311, PubMed:26642356, PubMed:26814970, PubMed:27374331, PubMed:28847925). Activation of NLRP3 inflammasome is also required for HMGB1 secretion; stimulating inflammatory responses (PubMed:22801494). Under resting conditions, ADP-bound NLRP3 is autoinhibited (By similarity). NLRP3 activation stimuli include extracellular ATP, nigericin, reactive oxygen species, crystals of monosodium urate or cholesterol, amyloid-beta fibers, environmental or industrial particles and nanoparticles, such as asbestos, silica, aluminum salts, cytosolic dsRNA, etc (PubMed:16407888, PubMed:16407889, PubMed:16407890, PubMed:18403674, PubMed:19362020, PubMed:37001519). Almost all stimuli trigger intracellular K(+) efflux (PubMed:23809161). These stimuli lead to membrane perturbation and activation of NLRP3 (By similarity). Upon activation, NLRP3 is transported to microtubule organizing center (MTOC), where it is unlocked by NEK7, leading to its relocalization to dispersed trans-Golgi network (dTGN) vesicle membranes and formation of an active inflammasome complex (PubMed:26814970, PubMed:34615873, PubMed:34861190). Associates with dTGN vesicle membranes by binding to phosphatidylinositol 4-phosphate (PtdIns4P) (PubMed:30487600). Shows ATPase activity (PubMed:34861190). Independently of inflammasome activation, regulates the differentiation of T helper 2 (Th2) cells and has a role in Th2 cell-dependent asthma and tumor growth (PubMed:26098997). During Th2 differentiation, required for optimal IRF4 binding to IL4 promoter and for IRF4-dependent IL4 transcription (PubMed:26098997). Binds to the consensus DNA sequence 5'-GRRGGNRGAG-3' (PubMed:26098997). May also participate in the transcription of IL5, IL13, GATA3, CCR3, CCR4 and MAF (PubMed:26098997).

Belongs to the NLRP family.
- Post-translational modifications
Phosphorylation at Ser-194 by MAPK8/JNK1 increases inflammasome activation by promoting deubiquitination by BRCC3 and NLRP3 homooligomerization (PubMed:28943315). Phosphorylation at Ser-803 by CSNK1A1 prevents inflammasome activation by preventing NEK7 recruitment (PubMed:34615873). Phosphorylation at Ser-3 in the pyrin domain inhibits homomultimerization of NLRP3 and activation of the NLRP3 inflammasome: dephosphorylation by protein phosphatase 2A (PP2A) promotes assembly of the NLRP3 inflammasome (PubMed:28465465). Phosphorylation at Ser-291 by PKD/PRKD1 promotes NLRP3 inflammasome assembly (PubMed:28716882). Phosphorylation by ERK1/MAPK3 promotes NLRP3 inflammasome assembly (By similarity). Phosphorylation by BTK (at Tyr-132, Tyr-136, Tyr-145 and Tyr-164) in the region that mediates binding to phosphatidylinositol phosphate, promotes relocalization of NLRP3 and assembly of the NLRP3 inflammasome (PubMed:34554188). Phosphorylation at Tyr-858 inhibits NLRP3 inflammasome assembly: dephosphorylation by PTPN22 promotes inflammasome activation (PubMed:27043286).

- Activity summary
NLRP3 also known as NALP3 or cryopyrin is a protein important for the inflammatory response. It is a component of the inflammasome which senses pathogenic microorganisms and stress. NLRP3 weighs around 118 kDa and is widely expressed in innate immune cells particularly macrophages and dendritic cells. Researchers often use techniques such as 'NLRP3 WB' (Western blot) and 'NLRP3 immunofluorescence' to study NLRP3 expression and localization.
- Biological function summary
NLRP3 is central to the body’s defense mechanism by participating in forming the inflammasome complex which activates caspase-1. This activation leads to the cleavage of pro-inflammatory cytokines like IL-1β and IL-18 into their active forms. NLRP3's function is essential for mounting an effective immune response to infections and damage signals. It senses a range of stimuli including crystalline substances and cellular stress triggering an immune response. Its expression is tightly regulated to prevent excessive inflammation.
- Pathways
The NLRP3 inflammasome is key in the innate immune response and inflammation pathways. It links cellular stress signals to inflammation through the activation of caspase-1 which is important for the IL-1 signaling pathway. NLRP3 interacts with other proteins like ASC (apoptosis-associated speck-like protein containing a CARD) to form the inflammasome complex which is a core part of the inflammatory signaling pathways and links innate and adaptive immunity.
- Associated diseases and disorders
NLRP3 has a significant role in inflammatory diseases and is linked to conditions like cryopyrin-associated periodic syndromes (CAPS) and gout. Mutations or dysregulation of NLRP3 lead to hyperactivation resulting in autoimmune and autoinflammatory conditions. NLRP3's interaction with IL-1 contributes to the excessive inflammatory response seen in these disorders. Understanding NLRP3's function in these pathways can inform therapeutic approaches targeting chronic inflammatory diseases.
