概述

Human FGF-19 is encoded by the FGF19 gene.FGF-19 belongs to the FGF-19 subfamily which has three members FGF-19,21,23.FGFs are classically considered to be paracrine factors and are known for their roles in tissue patterning and organogenesis during embryogenesis.By contrast,the FGF-19 subfamily has recently been shown to function in an endocrine manner.Members of this subfamily have poor ability of binding to heparin binding site which is a crucial factor in ligand-receptor complex formation.β-Klotho has been identified as co-factor required for FGF-19,21,23 signaling.It can obviously increase ligand-receptor affinity.Unlike most FGFs which bind to and activate more than one FGF receptor,FGF19 is a specific ligand for FGF R4.In FGF-19 transgenic mice,reducing liver triglycerides,increasing fatty acid oxidation,reducing glucose levels and improving insulin sensitivity can be observed.
