target relevance
Fibroblast growth factors (FGFs) comprise a family of at least eighteen structurally related proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentiation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family of type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after ligand binding.FGFR1 is 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.

Function
FUNCTION: Tyrosine-protein kinase that acts as a 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. {ECO:0000250|UniProtKB:P16092, ECO:0000269|PubMed:10830168, ECO:0000269|PubMed:11353842, ECO:0000269|PubMed:12181353, ECO:0000269|PubMed:1379697, ECO:0000269|PubMed:1379698, ECO:0000269|PubMed:15117958, ECO:0000269|PubMed:16597617, ECO:0000269|PubMed:17311277, ECO:0000269|PubMed:17623664, ECO:0000269|PubMed:18480409, ECO:0000269|PubMed:19224897, ECO:0000269|PubMed:19261810, ECO:0000269|PubMed:19665973, ECO:0000269|PubMed:20133753, ECO:0000269|PubMed:20139426, ECO:0000269|PubMed:21765395, ECO:0000269|PubMed:8622701, ECO:0000269|PubMed:8663044}.
Subellular location
SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. Nucleus. Cytoplasm, cytosol. Cytoplasmic vesicle. Note=After ligand binding, both receptor and ligand are rapidly internalized. Can translocate to the nucleus after internalization, or by translocation from the endoplasmic reticulum or Golgi apparatus to the cytosol, and from there to the nucleus.
Tissues
TISSUE SPECIFICITY: Detected in astrocytoma, neuroblastoma and adrenal cortex cell lines. Some isoforms are detected in foreskin fibroblast cell lines, however isoform 17, isoform 18 and isoform 19 are not detected in these cells. {ECO:0000269|PubMed:1652059}.
Structure
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:12181353, PubMed:16597617, PubMed:1697263, PubMed:1722683, PubMed:17623664, PubMed:8663044, PubMed:9655399). 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:1379697, PubMed:1656221, 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:18441324, PubMed:20422052). {ECO:0000250|UniProtKB:P16092, ECO:0000269|PubMed:10454568, ECO:0000269|PubMed:12181353, ECO:0000269|PubMed:1379697, ECO:0000269|PubMed:15117958, ECO:0000269|PubMed:1656221, ECO:0000269|PubMed:16597617, ECO:0000269|PubMed:1697263, ECO:0000269|PubMed:1722683, ECO:0000269|PubMed:17623664, ECO:0000269|PubMed:18441324, ECO:0000269|PubMed:19696444, ECO:0000269|PubMed:19966287, ECO:0000269|PubMed:20422052, ECO:0000269|PubMed:21765395, ECO:0000269|PubMed:8663044, ECO:0000269|PubMed:9655399}.
Post-translational modification
PTM: Autophosphorylated. Binding of FGF family members together with heparan sulfate proteoglycan or heparin promotes receptor dimerization and autophosphorylation on tyrosine residues. Autophosphorylation occurs in trans between the two FGFR molecules present in the dimer and proceeds in a highly ordered manner. Initial autophosphorylation at Tyr-653 increases the kinase activity by a factor of 50 to 100. After this, Tyr-583 becomes phosphorylated, followed by phosphorylation of Tyr-463, Tyr-766, Tyr-583 and Tyr-585. In a third stage, Tyr-654 is autophosphorylated, resulting in a further tenfold increase of kinase activity. Phosphotyrosine residues provide docking sites for interacting proteins and so are crucial for FGFR1 function and its regulation. {ECO:0000269|PubMed:16507368, ECO:0000269|PubMed:19224897, ECO:0000269|PubMed:19665973, ECO:0000269|PubMed:8622701}.; PTM: Ubiquitinated. FGFR1 is rapidly ubiquitinated by NEDD4 after autophosphorylation, leading to internalization and lysosomal degradation. CBL is recruited to activated FGFR1 via FRS2 and GRB2, and mediates ubiquitination and subsequent degradation of FGFR1. {ECO:0000269|PubMed:18480409, ECO:0000269|PubMed:21765395}.; PTM: N-glycosylated in the endoplasmic reticulum. The N-glycan chains undergo further maturation to an Endo H-resistant form in the Golgi apparatus. {ECO:0000269|PubMed:16335952, ECO:0000269|PubMed:16481405, ECO:0000269|PubMed:17311277}.
