Additional sequence informationEncodes the signal peptide and extracellular domain of human FGF R4 (aa1-201) was fused to the Fc region of human IgG1 (aa 93-330). The chimeric protein was expressed in modified human 293 cells.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at +4°C.
Constituents: 10% Trehalose, 1% Human serum albumin
ReconstitutionIt is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial.
Following reconstitution short-term storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.
Fibroblast growth factor receptor 4
Hydroxyaryl protein kinase
Protein tyrosine kinase
Tyrosine kinase related to fibroblast growth factor receptor
FunctionReceptor for acidic fibroblast growth factor. Does not bind to basic fibroblast growth factor. Binds FGF19.
Tissue specificityExpressed in gastrointestinal epithelial cells, pancreas, and gastric and pancreatic cancer cell lines.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Fibroblast growth factor receptor subfamily. Contains 3 Ig-like C2-type (immunoglobulin-like) domains. Contains 1 protein kinase domain.
Post-translational modificationsGlycosylated. Phosphorylated on tyrosine residue (By similarity). Phosphorylation requires the presence of a functional (phosphorylated) FGFR1 and not necessarily by means of FGFR heterodimerization.
Cellular localizationMembrane. Isoform 2 may be secreted.
