Recombinant Human Fibroblast Growth Factor 21
FGF21 is a member of the Fibroblast Growth Factor family of proteins. It is in the same endocrine signaling subfamily as FGF19 and FGF23. FGF21 is a heparin-binding ligand for FGFR1c and FGFR4 that requires the presence of beta-klotho. Expression of FGF21 mRNA has been observed in the liver, the thymus, and several types of adipose tissue. It has been shown to stimulate glucose incorporation in differentiated adipocytes, independent of insulin activity. It has been suggested that FGF21 also acts as key regulator in the adaptation to stress.
