FGFacidic (Fibroblast Growth Factor acidic)
FGFacidic is one of 23 known members of the FGF family. Proteins of this family play a central role during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGFacidic is a non-glycosylated heparin binding growth factor that is expressed in the brain, kidney, retina, smooth muscle cells, bone matrix, osteoblasts, astrocytes and endothelial cells. FGFacidic has the ability to signal through all the FGF receptors. Recombinant Human FGFacidic is a 16.8 kDa protein consisting of 141 amino acid residues.
