FGF-21 Proteins and Enzymes

FGF-21 (Fibroblast Growth Factor 21) is a member of an FGF subfamily that also includes FGF-19 and FGF-23. FGF-19 subfamily members lack a heparin binding domain, enabling them to freely circulate as endocrine factors and diffuse within tissues. FGF-21 signals through Klotho beta in complex with FGF receptors. It regulates cellular metabolism inclu...
