HSP90AA1 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\u003eLinking protein expression or modification states to neuronal activity, synaptic plasticity, and circuit phenotypes.\u003c\/li\u003e \u003cli\u003eStudying receptor\/ligand or scaffolding interactions that influence synapse organization and signaling.\u003c\/li\u003e \u003cli\u003eDeveloping quantitative assays to track neurodegeneration- or injury-associated molecular changes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. Binds bacterial lipopolysaccharide (LPS) et mediates LPS-induced inflammatory response, including TNF secretion by monocytes.\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 P07900 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P07900\/entry - NCBI Gene search (HSP90AA1) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=HSP90AA1 - PubMed search (HSP90AA1) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=HSP90AA1 - RCSB PDB search (HSP90AA1) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=HSP90AA1 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065269051757,"sku":"CSB-EP010802HU3-1MG","price":1812.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065387344237,"sku":"CSB-EP010802HU3-100UG","price":419.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065387377005,"sku":"CSB-EP010802HU3-20UG","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP010802HU3-SDS.jpg?v=1772476399","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-heat-shock-protein-hsp-90-alpha-hsp90aa1-partial-bhp10508868","provider":"BioHippo","version":"1.0","type":"link"}
