Known ligands include EGF, TGFA\/TGF-alpha, AREG, epigen\/EPGN, BTC\/betacellulin, epiregulin\/EREG and HBEGF\/heparin-binding EGF. Ligand binding triggers receptor homo- and\/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16, activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling. Also phosphorylates MUC1 and increases its interaction with SRC and CTNNB1\/beta-catenin. Positively regulates cell migration via interaction with CCDC88A\/GIV which retains EGFR at the cell membrane following ligand stimulation, promoting EGFR signaling which triggers cell migration. Plays a role in enhancing learning and memory performance. Plays a role in mammalian pain signaling (long-lasting hypersensitivity)\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStimulate cultured cells with EGFR (dose–response + time-course) and collect lysates.\u003c\/li\u003e\n\u003cli\u003eMeasure downstream markers after EGFR treatment (WB\/qPCR\/ELISA readouts).\u003c\/li\u003e\n\u003cli\u003eQuantify EGFR using standard curves in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eRun receptor binding kinetics for EGFR by SPR\/BLI (in vitro profiling).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (P00533) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/P00533 - NCBI Gene search (EGFR) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=EGFR - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=EGFR - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059324313965,"sku":"CSB-MP007479HUr8-1MG","price":2450.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059493429613,"sku":"CSB-MP007479HUr8-100UG","price":362.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059493462381,"sku":"CSB-MP007479HUr8-20UG","price":144.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-MP007479HUr8-SDS.jpg?v=1772280433","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-epidermal-growth-factor-receptor-egfr-partial-bhp10516651","provider":"BioHippo","version":"1.0","type":"link"}
