Function
Tyrosine-protein kinase that acts as a cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation and apoptosis. Plays an essential role in the regulation of chondrocyte differentiation, proliferation and apoptosis, and is required for normal skeleton development. Regulates both osteogenesis and postnatal bone mineralization by osteoblasts. Promotes apoptosis in chondrocytes, but can also promote cancer cell proliferation. Required for normal development of the inner ear. Phosphorylates PLCG1, CBL and FRS2. 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. Plays a role in the regulation of vitamin D metabolism. Mutations that lead to constitutive kinase activation or impair normal FGFR3 maturation, internalization and degradation lead to aberrant signaling. Over-expressed or constitutively activated FGFR3 promotes activation of PTPN11/SHP2, STAT1, STAT5A and STAT5B. Secreted isoform 3 retains its capacity to bind FGF1 and FGF2 and hence may interfere with FGF signaling.

- Sequence similarities
Belongs to the protein kinase superfamily. Tyr protein kinase family. Fibroblast growth factor receptor subfamily.
- Post-translational modifications
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. Phosphorylation at Tyr-724 is essential for stimulation of cell proliferation and activation of PIK3R1, STAT1 and MAP kinase signaling. Phosphorylation at Tyr-760 is required for interaction with PIK3R1 and PLCG1.

- Activity summary
FGFR3 or fibroblast growth factor receptor 3 is a tyrosine kinase receptor with a molecular mass of approximately 95 kDa. This receptor also known as CD333 primarily interacts with fibroblast growth factors. It resides on the cell surface and is predominately expressed in bone cartilage and the brain. FGFR3 plays a major role in cell growth regulation and differentiation affecting how cells respond to external signals.
- Biological function summary
FGFR3 participates in important processes such as chondrogenesis and osteogenesis which are essential for bone growth and development. The receptor operates within a complex system involving interactions with ligand-induced dimerization and autophosphorylation. This phosphorylation event activates the receptor's intrinsic kinase activity further triggering downstream signaling pathways for cellular responses.
- Pathways
FGFR3 is involved with the MAPK/ERK and PI3K/AKT pathways which play significant roles in cell proliferation differentiation and survival. FGFR3 links closely with FGF ligands and similar receptor types such as FGFR1 and FGFR2 within these pathways. Differences in pathway activation can lead to diverse biological responses illustrating its pivotal role in maintaining cellular homeostasis.
- Associated diseases and disorders
FGFR3 mutations have significant links to skeletal disorders most notably achondroplasia characterized by short limbs and abnormal bone growth. FGFR3 also associates with bladder cancer where overactivity of the receptor leads to increased cell proliferation and survival. Mutations in FGFR3 often correlate with these conditions impacting signaling pathways and interacting with proteins such as PTPN11 highlighting its critical role in pathogenesis.
