Protein Description

FGF-8b(FGF-8) is belonging to the FGF family, which is widely expressed during embryogenesis. There are four  known  alternate  spliced  forms of FGF-8: FGF-8a, FGF-8b, FGF-8e and FGF-8f. Proteins of this family play an important role in the regulation of embryonic development, cell proliferation, cell differentiation and cell migration. FGF-8b is required for normal brain,  eye,  ear and limb  development  during  embryogenesis. It is also required for normal development of the gonadotropin-releasing hormone (GnRH) neuronal system during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-8b shows the strongest receptor affinity and oncogenic transforming capacity.
