Function
FGFR4_HUMAN 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.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]
Publication Abstract from PubMed
Abnormal activation of the fibroblast growth factor 19 (FGF19)/fibroblast growth factor receptor 4 (FGFR4) signaling pathway has been shown to drive the proliferation of a significant portion of hepatocellular carcinoma (HCC). Resistance and toxicity are serious drawbacks that have been observed upon use of the current first- and second-line treatment options for HCC, therefore warranting the investigation of alternative therapeutic approaches. We report the development and biological characterization of a covalent inhibitor that is highly potent and exquisitely specific to FGFR4. The crystal structure of this inhibitor in complex with FGFR4 was solved, confirming its covalent binding and revealing its binding mode. We also describe the first clickable probe for FGFR4 that can be used to directly measure target engagement in cells. Our compound exhibited great antitumor activity in HCC cell lines and tumor xenograft models. These results provide evidence of a promising therapeutic lead for the treatment of a subset of HCC patients.
