Amino acids 1-536 form the expressed segment for recombinant Human NLRP3. The calculated molecular weight for this NLRP3 protein is 66.1 kDa. The NLRP3 protein was expressed in e.coli. Fusion of the N-terminal 6xHis tag into the NLRP3 encoding gene fragment was conducted, allowing for easier detection and purification of the NLRP3 protein in subsequent stages.

The human NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) mainly serves as a critical component of the inflammasome, a multiprotein complex involved in immune responses. NLRP3 activation leads to the cleavage and release of pro-inflammatory cytokines, triggering inflammation in response to cellular stress or pathogens. In immunology and inflammatory research, studying NLRP3 provides insights into innate immunity, inflammatory pathways, and autoimmune diseases. NLRP3's involvement in various pathologies, including neurodegenerative disorders and metabolic diseases, makes it a target in diverse research areas. Investigating NLRP3 offers potential applications in understanding and modulating immune responses, inflammation, and related diseases.

We plan to use this for an SPR study, and therefore need to know that it's correctly folded. How could we do this?


The protein in stock is in buffer HEPES or PBS. It's suited for the SPR experiment. As to the fold of this protein, we haven't tested it in our lab, so we can't guarantee it will be correctly folded. We suggest you purchase a small package for a try at first.

Target Background

As the sensor component of the NLRP3 inflammasome, plays a crucial role in innate immunity and inflammation. In response to pathogens and other damage-associated signals, initiates the formation of the inflammasome polymeric complex, made of NLRP3, PYCARD and CASP1 (and possibly CASP4 and CASP5). Recruitment of proCASP1 to the inflammasome promotes its activation and CASP1-catalyzed IL1B and IL18 maturation and secretion in the extracellular milieu. Activation of NLRP3 inflammasome is also required for HMGB1 secretion. The active cytokines and HMGB1 stimulate inflammatory responses. Inflammasomes can also induce pyroptosis, an inflammatory form of programmed cell death. Under resting conditions, NLRP3 is autoinhibited. NLRP3 activation stimuli include extracellular ATP, reactive oxygen species, K(+) efflux, crystals of monosodium urate or cholesterol, amyloid-beta fibers, environmental or industrial particles and nanoparticles, cytosolic dsRNA, etc. However, it is unclear what constitutes the direct NLRP3 activator. Activation in presence of cytosolic dsRNA is mediated by DHX33. 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. During Th2 differentiation, required for optimal IRF4 binding to IL4 promoter and for IRF4-dependent IL4 transcription. Binds to the consensus DNA sequence 5'-GRRGGNRGAG-3'. May also participate in the transcription of IL5, IL13, GATA3, CCR3, CCR4 and MAF.
