NLRP1 refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eUsing recombinant proteins to enable quantitative binding measurements and reagent benchmarking.\u003c\/li\u003e \u003cli\u003eStudying domain- and isoform-specific effects in pathway models and interaction networks.\u003c\/li\u003e \u003cli\u003eDeveloping robust, reproducible assays that connect molecular readouts to cellular phenotypes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Acts as the sensor component of the NLRP1 inflammasome, which mediates inflammasome activation in response to various pathogen-associated signals, leading to subsequent pyroptosis . Inflammasomes are supramolecular complexes that assemble in the cytosol in response to pathogens and other damage-associated signals and play critical roles in innate immunity and inflammation . Acts as a recognition receptor (PRR): recognizes specific pathogens and other damage-associated signals, such as cleavage by human rhinoviruses 14 and 16 (HRV-14 and HRV-16), double-stranded RNA or Val-boroPro inhibitor, and mediates the formation of the inflammasome polymeric complex composed of NLRP1, CASP1 and PYCARD\/ASC . In response to pathogen-associated signals, the N-terminal part of NLRP1 is degraded by the proteasome, releasing the cleaved C-terminal part of the protein (NACHT, LRR and PYD domains-containing protein 1, C-terminus), which polymerizes and associates with PYCARD\/ASC to initiate the formation of the inflammasome complex: the NLRP1 inflammasome recruits pro-caspase-1 (proCASP1) and promotes caspase-1 (CASP1) activation, which subsequently cleaves and activates inflammatory cytokines IL1B and IL18 and gasdermin-D (GSDMD), leading to pyroptosis . Activation of NLRP1 inflammasome is also required for HMGB1 secretion; the active cytokines and HMGB1 stimulate inflammatory responses . Binds ATP and shows ATPase activity . Plays an important role in antiviral immunity and inflammation in the human airway epithelium . Specifically recognizes a number of pathogen-associated signals: upon infection by human rhinoviruses 14 and 16 (HRV-14 and HRV-16), NLRP1 is cleaved and activated which triggers NLRP1-dependent inflammasome activation and IL18 secretion . Positive-strand RNA viruses such as. Semliki forest virus and long dsRNA activate the NLRP1 inflammasome, triggering IL1B release in a NLRP1-dependent fashion . Acts as a direct sensor for long dsRNA and thus RNA virus infection . May also be activated by muramyl dipeptide (MDP), a fragment of bacterial peptidoglycan, in a NOD2-dependent manner .; [NACHT, LRR and PYD domains-containing protein 1]: Constitutes the precusor of the NLRP1 inflammasome, which mediates autoproteolytic processing within the FIIND domain to generate the N-terminal and C-terminal parts, which are associated non-covalently in absence of pathogens and other damage-associated signals.; [NACHT, LRR and PYD domains-containing protein 1, N-terminus]: Regulatory part that prevents formation of the NLRP1 inflammasome: in absence of pathogens and other damage-associated signals, interacts with the C-terminal part of NLRP1 (NACHT, LRR and PYD domains-containing protein 1, C-terminus), preventing activation of the NLRP1 inflammasome . In response to pathogen-associated signals, this part is ubiquitinated and degraded by the proteasome, releasing the cleaved C-terminal part of the protein, which polymerizes and forms the NLRP1 inflammasome .; [NACHT, LRR and PYD domains-containing protein 1, C-terminus]: Constitutes the active part of the NLRP1 inflammasome . In absence of pathogens and other damage-associated signals, interacts with the N-terminal part of NLRP1 (NACHT, LRR and PYD domains-containing protein 1, N-terminus), preventing activation of the NLRP1 inflammasome . In response to pathogen-associated signals, the N-terminal part of NLRP1 is degraded by the proteasome, releasing this form, which polymerizes and associates with PYCARD\/ASC to form of the NLRP1 inflammasome complex: the NLRP1 inflammasome complex then directly recruits pro-caspase-1 (proCASP1) and promotes caspase-1 (CASP1) activation, leading to gasdermin-D (GSDMD) cleavage and subsequent pyroptosis .; [Isoform 2]: It is unclear whether is involved in inflammasome formation. It is not cleaved within the FIIND domain, does not assemble into specks, nor promote IL1B release . However, in an vitro cell-free system, it has been shown to be activated by MDP .\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAssay and standard development for immunoassays or binding-based detection methods.\u003c\/li\u003e \u003cli\u003eProtein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.\u003c\/li\u003e \u003cli\u003eStructure–function analysis, including domain mapping or evaluation of sequence variants.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for Q96AM0 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/Q96AM0\/entry - NCBI Gene search (NLRP1) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=NLRP1 - PubMed search (NLRP1) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=NLRP1 - RCSB PDB search (NLRP1) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=NLRP1 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065294971245,"sku":"CSB-EP871630HU-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065441673581,"sku":"CSB-EP871630HU-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065441706349,"sku":"CSB-EP871630HU-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP871630HU-SDS.jpg?v=1772476541","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-nlrp1-protein-nlrp1-bhp10509647","provider":"BioHippo","version":"1.0","type":"link"}
