Related Product Information for FGFR3b recombinant protein

It is a single-pass transmembrane protein composed of three extracellular Ig-like domains, a transmembrane region, and a tyrosine kinase domain (1, 2). Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation and apoptosis (3, 4, 5, 6). Plays an essentialrole 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 signalling cascades(6). Activation of PLCG1 leads to the production of the cellular signalling moleculesdiacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggersrecruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS,MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signalling pathway, as well as of the AKT1signalling pathway (7, 8, 9). 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 signalling (10, 11). Over-expressed orconstitutively activated FGFR3 promotes activation of PTPN11/SHP2, STAT1, STAT5A andSTAT5B. Secreted isoform 3 retains its capacity to bind FGF1 and FGF2 and hence mayinterfere with FGF signalling.
FGFR3b is an alternatively spliced isoform representing epithelial variant of FGFR3.

NCBI Description

This gene encodes a member of the fibroblast growth factor receptor (FGFR) family, with its amino acid sequence being highly conserved between members and among divergent species. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Mutations in this gene lead to craniosynostosis and multiple types of skeletal dysplasia. Three alternatively spliced transcript variants that encode different protein isoforms have been described.

Uniprot Description

FGFR3: a receptor tyrosine kinase of the highly-conserved FGFR family that binds fibroblast growth factor (FGF). Mutations are associated with thanatophoric dysplasia (TD), craniosynostosis Adelaide type, many craniosynostotic syndromes and bone malformations. Three splice-variant isoforms have been described. Activating point mutations cause dwarfism, including achondroplasia, hypochrondroplasia and thanatophoric dysplasia, and facial and other morphogenetic disorders, including Crouzon syndrome, craniosynostosis Adelaide type, San Diego skeletal displasia and Muenke syndrome. Translocations t(4;14) involving the IgH region are common in multiple myeloma and frequently involve FGFR3. Activated FGFR3 found in 30% of bladder cancers and several cervical cancers, but not in other tumors. Two mutations found in colorectal cancer.
