FGF-22 Proteins and Enzymes

Fibroblast growth factor-22 (FGF-22) is a 23 kDa, nonglycosylated member of the FGF-7 subfamily, FGF family of heparin-binding growth factors. The human FGF-22 precursor is 170 amino acids (aa) in length, and contains a 22 aa signal sequence with a 148 aa mature region.

FGF-22 is synthesized by at least three cell types; keratinocytes, ne...
