CC   -!- FUNCTION: Tyrosine-protein kinase that acts as a cell-surface receptor
CC       for fibroblast growth factors and plays a role in the regulation of
CC       cell proliferation, differentiation and migration, and in regulation of
CC       lipid metabolism, bile acid biosynthesis, glucose uptake, vitamin D
CC       metabolism and phosphate homeostasis. Required for normal down-
CC       regulation of the expression of CYP7A1, the rate-limiting enzyme in
CC       bile acid synthesis, in response to FGF19. Phosphorylates PLCG1 and
CC       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       Promotes SRC-dependent phosphorylation of the matrix protease MMP14 and
CC       its lysosomal degradation. FGFR4 signaling is down-regulated by
CC       receptor internalization and degradation; MMP14 promotes
CC       internalization and degradation of FGFR4. Plays a role in postnatal
CC       lung development. May be involved in the development of skeletal muscle
CC       cell lineages. {ECO:0000269|PubMed:10809780,

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, FGF16, FGF17, FGF18, FGF19, FGF21 and
CC       FGF23 (in vitro). Binding affinity for FGF family members is enhanced
CC       by interactions between FGFs and heparan sulfate proteoglycans.
CC       Interacts with KLB; this strongly increases the affinity for FGF19 and
CC       FGF23. Affinity for FGF19 is strongly increased by KLB and sulfated
CC       glycosaminoglycans. KLB and KL both interact with the core-glycosylated
CC       FGFR4 in the endoplasmic reticulum and promote its degradation, so that
CC       only FGFR4 with fully mature N-glycans is expressed at the cell
CC       surface. Identified in a complex with NCAM1, CDH2, PLCG1, FRS2, SRC,
CC       SHC1, GAP43 and CTTN. Interacts with MMP14 and HIP1. Interacts with
CC       STAT3 (By similarity). {ECO:0000250|UniProtKB:P22455}.

CC         IsoId=Q03142-2; Sequence=VSP_017545;
CC   -!- TISSUE SPECIFICITY: Isoform 1 and isoform 2 are expressed in lung and
CC       proliferating myoblasts and myotubes of primary myogenic cells (at
CC       protein level). Isoform 1 and isoform 2 are expressed in liver, muscle,
CC       spleen, heart, lung, kidney and in primary myogenic cells.
CC       {ECO:0000269|PubMed:1723680, ECO:0000269|PubMed:18186042}.
CC   -!- DEVELOPMENTAL STAGE: Expressed in the developing gut endoderm, in
CC       myotomally derived skeletal muscle, the adrenal cortex, kidney and
CC       condensing cartilage. {ECO:0000269|PubMed:1723680}.
CC   -!- INDUCTION: Isoform 1 and isoform 2 are up-regulated by estradiol during
CC       myogenic differentiation and down-regulated in fully developed
CC       myotubes. {ECO:0000269|PubMed:18186042}.
CC   -!- PTM: N-glycosylated. Isoform 1 and isoform 2 are glycosylated. Full
CC       maturation of the glycan chains in the Golgi is essential for high
CC       affinity interaction with FGF19 (By similarity). {ECO:0000250}.
CC   -!- PTM: Ubiquitinated. Subject to proteasomal degradation when not fully
CC       glycosylated (By similarity). {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       Isoform 1 and isoform 2 are phosphorylated on tyrosine residues (By
CC       similarity). {ECO:0000250}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype. Mice display an elevated
CC       bile acid pool and elevated excretion of bile acids, due to loss of
CC       normal regulation of CYP7A1, the rate-limiting enzyme in bile acid
CC       synthesis. When on a normal diet, mice are prone to develop increased
CC       levels of white adipose tissue, hyperlipidemia, hypercholesterolemia,
CC       glucose intolerance and insulin resistance. 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:10809780, ECO:0000269|PubMed:17664243,

CC       ECO:0000269|PubMed:9716527}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC       kinase family. Fibroblast growth factor receptor subfamily.
