CYP3A5 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 A cytochrome P450 monooxygenase involved in the metabolism of steroid hormones and vitamins . Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds . Exhibits high catalytic activity for the formation of catechol estrogens from 17beta-estradiol (E2) and estrone (E1), namely 2-hydroxy E1 and E2 . Catalyzes 6beta-hydroxylation of the steroid hormones testosterone, progesterone, and androstenedione . Catalyzes the oxidative conversion of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) . Further metabolizes all trans-retinoic acid (atRA) to 4-hydroxyretinoate and may play a role in hepatic atRA clearance . Also involved in the oxidative metabolism of xenobiotics, including calcium channel blocking drug nifedipine and immunosuppressive drug cyclosporine .\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 P20815 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P20815\/entry - NCBI Gene search (CYP3A5) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CYP3A5 - PubMed search (CYP3A5) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CYP3A5 - RCSB PDB search (CYP3A5) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=CYP3A5 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065323544941,"sku":"CSB-EP006441HU-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065497936237,"sku":"CSB-EP006441HU-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065497969005,"sku":"CSB-EP006441HU-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP006441HU-SDS.jpg?v=1772476682","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-cytochrome-p450-3a5-cyp3a5-bhp10510567","provider":"BioHippo","version":"1.0","type":"link"}
