• Subunit: Monomer. Homodimer after ligand binding. Interacts predominantly with FGF1 and FGF2, but can also interact with FGF3, FGF4, FGF5, FGF6, FGF8, FGF10, FGF19, FGF21, FGF22 and FGF23 (in vitro) (PubMed:1697263, PubMed:1722683, PubMed:8663044, PubMed:9655399, PubMed:12181353, PubMed:16597617, PubMed:17623664). Ligand specificity is determined by tissue-specific expression of isoforms, and differences in the third Ig-like domain are crucial for ligand specificity. Affinity for fibroblast growth factors (FGFs) is increased by heparan sulfate glycosaminoglycans that function as coreceptors. Likewise, KLB increases the affinity for FGF19, FGF21 and FGF23 (PubMed:19966287). Interacts (phosphorylated on Tyr-766) with PLCG1 (via SH2 domains) (PubMed:1656221, PubMed:1379697, PubMed:21765395). Interacts with FRS2 (PubMed:21765395). Interacts with RPS6KA1 (PubMed:15117958). Interacts (via C-terminus) with NEDD4 (via WW3 domain) (PubMed:21765395). Interacts with KL (By similarity). Interacts with SHB (via SH2 domain) (PubMed:12181353). Interacts with GRB10 (PubMed:10454568). Interacts with ANOS1; this interaction does not interfere with FGF2-binding to FGFR1, but prevents binding of heparin-bound FGF2 (PubMed:19696444). Interacts with SOX2 and SOX3. Interacts with FLRT1, FLRT2 and FLRT3 (By similarity). Found in a ternary complex with FGF1 and ITGAV:ITGB3 (PubMed:20422052, PubMed:18441324).
• Entry Function: Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of embryonic development, cell proliferation, differentiation and migration. 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.

NCBI Description

The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

Uniprot Description

FGFR1: a receptor tyrosine kinase of the highly-conserved fibroblast growth factor receptor (FGFR). Binds both acidic and basic fibroblast growth factors and is involved in limb induction. Point mutations cause Pfeffer syndrome (finger and toe malformations and other skeletal errors) and dominant Kallmann syndrome 2. Stem cell leukemia lymphoma syndrome (SCLL) may be caused by a t(8;13)(p12;q12) translocation that fuses a zinc finger gene, ZNF198, to FGFR1. Various myeloproliferative disorders have been linked to translocations that fuse FGFR1 to FOP, FIM, CEP1 or the atypical kinase, Bcr. Inhibitor: SU5402. 20 isoforms of the human protein produced by alternative splicing have been described.
