FGFR4 is highly expressed in embryonic tissues and is involved in embryonic development, angiogenesis, and tissue differentiation. The expression of FGFR4 in adult tissues is restricted to actively developing tissues. In adults, FGFR4 regulates bile acid synthesis, metabolism, muscle development, and tissue healing, among other things. FGFR4 performs these functions via interacting with FGF19. FGFR4 dysregulation has been linked to the development of a variety of cancers. Overexpression of FGFR4 has been found in multiple human cancers, including breast cancer, liver cancer, and colon cancer, and has been associated with a shorter life expectancy. Furthermore, high FGFR4 expression is related to cancer resistance to chemotherapy and radiotherapy.

Mammalian cells are transfected with plasma vectors containing FGFR4 antibody genes, allowing for both recombinant FGFR4 antibody expression and secretion to the medium. Collecting the cell supernatant and purifying to obtain the recombinant FGFR4 antibody by Affinity-chromatography. This recombinant FGFR4 antibody has been validated to detect the FGFR4 protein of Human in the ELISA, IHC.

Target Background

Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays a role in the regulation of cell proliferation, differentiation and migration, and in regulation of lipid metabolism, bile acid biosynthesis, glucose uptake, vitamin D metabolism and phosphate homeostasis. Required for normal down-regulation of the expression of CYP7A1, the rate-limiting enzyme in bile acid synthesis, in response to FGF19. Phosphorylates PLCG1 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. Promotes SRC-dependent phosphorylation of the matrix protease MMP14 and its lysosomal degradation. FGFR4 signaling is down-regulated by receptor internalization and degradation; MMP14 promotes internalization and degradation of FGFR4. Mutations that lead to constitutive kinase activation or impair normal FGFR4 inactivation lead to aberrant signaling.
