Required for normal mesoderm patterning and correct axial organization during embryonic development, normal skeletogenesis and normal development of the gonadotropin-releasing hormone (GnRH) neuronal system. Phosphorylates PLCG1, FRS2, GAB1 and SHB. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1\/ERK2, MAPK3\/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Promotes phosphorylation of SHC1, STAT1 and PTPN11\/SHP2. In the nucleus, enhances RPS6KA1 and CREB1 activity and contributes to the regulation of transcription. FGFR1 signaling is down-regulated by IL17RD\/SEF, and by FGFR1 ubiquitination, internalization and degradation.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReagent standardization: using recombinant proteins as reference materials for quantitative calibration and cross-study comparability.\u003c\/li\u003e\n\u003cli\u003eInteraction-focused studies: mapping binding partners, affinity changes, and structure–function relationships across variants or domains.\u003c\/li\u003e\n\u003cli\u003eMulti-omic readouts: combining recombinant perturbations with transcript, protein, and functional endpoints to connect mechanism to phenotype.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAssay development and validation: use as a defined input or standard where protein identity is required.\u003c\/li\u003e\n\u003cli\u003eBinding studies: evaluate interaction strength and specificity using plate-based or biophysical formats.\u003c\/li\u003e\n\u003cli\u003eCell-response profiling: add protein to cultured cells and interpret downstream marker changes with appropriate controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpretation is most robust when signal changes are evaluated relative to matched controls (buffer-only, unrelated protein controls, or pathway controls) and when readouts are compared across dose and time.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIsoforms and PTMs can influence binding and activity; ensure the expressed region and expression system match your experimental needs.\u003c\/li\u003e\n\u003cli\u003eSpecies differences may affect receptor binding or antibody recognition; confirm species\/source alignment with your model.\u003c\/li\u003e\n\u003cli\u003eUse concept-level controls such as negative controls (no protein), matrix controls, or orthogonal readouts to support conclusions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt keyword search: https:\/\/www.uniprot.org\/uniprotkb?query=FGFR1 - NCBI Gene search: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=FGFR1 - PubMed search: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=FGFR1 - Ensembl search: https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=FGFR1 - Reactome Pathway Browser: https:\/\/reactome.org\/content\/query?q=FGFR1 --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053091709293,"sku":"CSB-YP008642HUa4-1MG","price":2010.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53053280518509,"sku":"CSB-YP008642HUa4-100UG","price":470.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53053280551277,"sku":"CSB-YP008642HUa4-20UG","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-YP008642HUa4-SDS.jpg?v=1772173058","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-fibroblast-growth-factor-receptor-1-fgfr1-partial-bhp10505498","provider":"BioHippo","version":"1.0","type":"link"}
