FGF-20 is a secreted heparin binding growth factor that is a member of the FGF family. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-20 signals through the FGFR 2c and 3c and is expressed during limb and brain development. Recombinant human FGF-20 is a 23.2 kDa protein containing 209 amino acid residues.
