| Background | Fibroblast growth factor 21 (FGF-21) is a member of the FGF gene family. Based on its structure, FGF-21 is further classified into a subfamily of FGFs along with FGF-19 and-23. At the amino acid sequence level, mature mouse FGF-21 is 81% and 92% identical to mature human and rat FGF-21, respectively.The biological activity of FGF-21 requires binding to Klotho beta, a co-receptor that is in complex with cell surface FGF receptors (FGF R). Binding of FGF-21 to Klotho beta facilitates FGF R activation and autophosphorylation resulting in the initiation of multiple downstream signaling cascades. FGF-21 cannot independently bind to FGF Rs, thus its effects are restricted to target tissues that express Klotho beta. FGF-21 functions as a physiological regulator of cellular metabolism, including glucose uptake in adipocytes and cellular sensitivity to insulin. FGF-21 is basally expressed in the pancreas, thymus, and liver, as well as in adipose tissue.Modulation of FGF-21 expression is associated with a number of metabolic disorders, including obesity and diabetesactivity |
