CC -!- FUNCTION: Tyrosine-protein kinase that acts as cell-surface receptor
CC for fibroblast growth factors and plays an essential role in the
CC regulation of cell proliferation, differentiation and apoptosis. Plays
CC an essential role in the regulation of chondrocyte differentiation,
CC proliferation and apoptosis, and is required for normal skeleton
CC development. Regulates both osteogenesis and postnatal bone
CC mineralization by osteoblasts. Promotes apoptosis in chondrocytes, but
CC can also promote cancer cell proliferation. Phosphorylates PLCG1, CBL
CC and FRS2. Ligand binding leads to the activation of several signaling
CC cascades. Activation of PLCG1 leads to the production of the cellular
CC signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate.
CC Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and
CC SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the
CC MAP kinase signaling pathway, as well as of the AKT1 signaling pathway
CC (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl-

CC ChEBI:CHEBI:82620, ChEBI:CHEBI:456216; EC=2.7.10.1;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10028};
CC -!- ACTIVITY REGULATION: Present in an inactive conformation in the absence
CC of bound ligand. Ligand binding leads to dimerization and activation by
CC autophosphorylation on tyrosine residues (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Monomer. Homodimer after ligand binding (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass type I
CC membrane protein {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Undetectable in the adult skeletal muscle. Low
CC levels of expression were detected in the liver, lung and kidney.
CC Medium levels of expression were detected in the heart, spleen,
CC intestine and eye. Highest expression is observed in the testis.
CC -!- DEVELOPMENTAL STAGE: Maternally transcript whose a low level of
CC expression persists during the cleavage and gastrula stages and a
CC significant increase was observed at the end of the gastrula stage.
CC Mainly localized to the ectoderm at the early gastrula stage and then
CC shifted to the embryonic neural tissues, whereas adult brain had
CC decreased levels of expression. Strong expression in the germinal
CC epithelium of the embryonic brain (especially the diencephalon and
CC rhombencephalon) and neural tube, in the lens and the cranial ganglia.
CC The epithelium of the developing gut, like the pharynx and esophagus,
CC also prominently expressed it. Other sites of expression were found in
CC the liver and in the mesenchymal condensation sites of branchial
CC arches. {ECO:0000269|PubMed:8006062}.
CC -!- DOMAIN: The second and third Ig-like domains directly interact with
CC fibroblast growth factors (FGF) and heparan sulfate proteoglycans.
CC {ECO:0000250}.
CC -!- PTM: Autophosphorylated. Binding of FGF family members together with
CC heparan sulfate proteoglycan or heparin promotes receptor dimerization
CC and autophosphorylation on tyrosine residues. Autophosphorylation
CC occurs in trans between the two FGFR molecules present in the dimer (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC kinase family. Fibroblast growth factor receptor subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00159}.
