Protein Description

FGF-4 is a heparin binding growth factor that belongs to the fibroblast growth factor family. FGF- 4 is proposed to play a physiologically relevant role in the regulation of embryonic development, cell proliferation, and cell differentiation. It is required for normal limb and cardiac valve development during embryogenesis.
