Description
FGF-21 is a unique member of FGF super family that is reported to be primarily produced by the liver. FGF-21 has recently been shown to have beneficial effects on a variety of metabolic parameters, including glucose and lipid metabolism and insulin sensitivity in animal models and is thought to exert potent antidiabetic and lipid-lowering agent of obesity and type 2 diabetes mellitus. FGF-21 activity depends on membrane protein beta Klotho that physically complexes with various FGF receptors, thus conferring them the ability to bind FGF-21 and activate downstream signaling pathways. Recombinant human FGF-21 protein, fused to His-tag at N-terminus, was expressed in E Coli and purified by using conventional chromatography techniques
