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. Required for normal
CC development of the inner ear. Phosphorylates PLCG1, CBL and FRS2.
CC Ligand binding leads to the activation of several signaling cascades.
CC Activation of PLCG1 leads to the production of the cellular signaling
CC 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 Plays a role in the regulation of vitamin D metabolism. Mutations that
CC lead to constitutive kinase activation or impair normal FGFR3
CC maturation, internalization and degradation lead to aberrant signaling.
CC Over-expressed or constitutively activated FGFR3 promotes activation of
CC STAT1, STAT5A and STAT5B. Plays a role in postnatal lung development.

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. Interacts with FGF1,
CC FGF2, FGF4, FGF6; FGF8, FGF9, FGF10, FGF17, FGF18, FGF19, FGF20 and
CC FGF23 (in vitro). Interacts with KLB. Affinity for fibroblast growth
CC factors (FGFs) is increased by heparan sulfate glycosaminoglycans that
CC function as coreceptors. Likewise, KLB increases the affinity for FGF19
CC and FGF21. Interacts with PIK3R1, PLCG1, SOCS1 and SOCS3 (By
CC similarity). {ECO:0000250}.
CC -!- INTERACTION:

CC Q61851-1; O35082: Kl; NbExp=2; IntAct=EBI-15820536, EBI-1570828;
CC -!- SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane
CC protein. Cytoplasmic vesicle {ECO:0000250}. Endoplasmic reticulum
CC {ECO:0000250}. Note=The activated receptor is rapidly internalized and
CC degraded. Detected in intracellular vesicles after internalization of
CC the autophosphorylated receptor (By similarity). {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1; Synonyms=IIIc;
CC IsoId=Q61851-1; Sequence=Displayed;
CC Name=2; Synonyms=IIIb;
CC IsoId=Q61851-2; Sequence=VSP_002990;
CC -!- TISSUE SPECIFICITY: In embryo, expressed in heart, lung, kidney, skin,
CC head and liver but not in muscle. In adult, highest levels in brain.
CC Also expressed in liver, lung, kidney, testis, ovary and uterus. Very
CC low levels in heart, thymus, spleen and muscle.
CC -!- DEVELOPMENTAL STAGE: Expressed in embryos from mid-gestation and in
CC adult.
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.
CC Phosphorylation at Tyr-719 is essential for stimulation of cell
CC proliferation and activation of PIK3R1, STAT1 and MAP kinase signaling.
CC Phosphorylation at Tyr-755 is required for interaction with PIK3R1 and
CC PLCG1 (By similarity). {ECO:0000250}.
CC -!- PTM: Ubiquitinated. Is rapidly ubiquitinated after ligand binding and
CC autophosphorylation, leading to receptor internalization and
CC degradation. Subject to both proteasomal and lysosomal degradation (By
CC similarity). {ECO:0000250}.
CC -!- PTM: N-glycosylated in the endoplasmic reticulum. The N-glycan chains
CC undergo further maturation to an Endo H-resistant form in the Golgi
CC apparatus (By similarity). {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Mice exhibit defects in their skeleton, including
CC kyphosis, scoliosis, crooked tails and curvature and overgrowth of long
CC bones and vertebrae. This bone dysplasia is due to defects in the
CC regulation of chondrocyte proliferation and differentiation in the
CC cartilaginous growth plate. Mice also display inner ear defects
CC including failure of pillar cell differentiation and tunnel of Corti
CC formation, resulting in profound deafness. Mice lacking both FGFR3 and
CC FGFR4 display pronounced dwarfism, and while their lungs appear normal
CC at birth, they are completely blocked in alveogenesis and do not form
CC secondary septae to delimit alveoli. These mice also show elevated
CC serum levels of 1,25-dihydroxyvitamin D3 and reduced serum phosphorus
CC levels. {ECO:0000269|PubMed:21561999, ECO:0000269|PubMed:8601314,
CC ECO:0000269|PubMed:8630492, ECO:0000269|PubMed:9716527}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC kinase family. Fibroblast growth factor receptor subfamily.
