GtoPdb Ligand ID: 11545

Synonyms: fibroblast growth factor 19
Comment: FGF-19 is a fibroblast growth factor that mediates a wide range of mitogenic and cell survival activities. It is one of the endogenous ligands for fibroblast growth factor receptor 4 (FGFR4) [2]. FGF-19 is a major player in the gut-liver axis that maintains bile acid homeostasis, its expression is induced in the liver under cholestatic and cirrhotic conditions, and it is implicated in the development of hepatocellular carcinoma (HCC).

Bioactivity Comments
Although FGFR4 can bind several FGFs, FGF-19 interacts only with FGFR4 [2]. Klotho-β (KLB) is required for the FGF-19-FGFR4 interaction.
