The NLRP3 protein acts as a sensor in the NLRP3 inflammasome, which is activated in response to membrane defects. It forms a complex with CASP1 and PYCARD/ASC, promotes the release of IL1B, IL18 and GSDMD, and induces pyroptosis. NLRP3 Protein, Human (His) is the recombinant human-derived NLRP3, expressed by E. coli , with C-6*His labeled tag. ,

Human

NLRP3 protein serves as the sensor component of the NLRP3 inflammasome, orchestrating the activation of the inflammasome in response to various stimuli that compromise membrane integrity, leading to the secretion of inflammatory cytokines IL1B and IL18, as well as pyroptosis. In the presence of pathogens or damage-associated signals affecting membrane integrity, NLRP3 initiates the assembly of the inflammasome complex, comprising NLRP3, CASP1, and PYCARD/ASC. This results in the recruitment and activation of pro-caspase-1, which subsequently cleaves and activates IL1B, IL18, and gasdermin-D (GSDMD), promoting cytokine release and pyroptotic cell death. Activation stimuli include extracellular ATP, nigericin, reactive oxygen species, crystals, amyloid-beta fibers, and various particles or nanoparticles. Intriguingly, NLRP3 also plays a role in regulating the differentiation of T helper 2 (Th2) cells, contributing to Th2 cell-dependent processes such as asthma and tumor growth. During Th2 differentiation, NLRP3 is involved in optimal IRF4 binding to the IL4 promoter and IRF4-dependent IL4 transcription, highlighting its multifaceted functions beyond inflammasome activation.
