CD14 Rat mAb (F1070-GRP)

Fibroblast growth factor 9 (glia-activating factor), also known as FGF9 is a glycosylated neurotrophic polypeptide highly expressed in brain.1 It is a member of the fibroblast growth factor (FGF) family that possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein was isolated as a secreted factor that exhibits a growth-stimulating effect on cultured glial cells. In nervous system, this protein is produced mainly by neurons and may be important for glial cell development. FGF-9 has sequence similarity of approximately 30% to other members of the family of fibroblast growth factors.2 It is highly related to FGF-16. FGF-9 has been shown to mediate its effects by binding to FGF receptors. It efficiently activates the FGFR2c splice form of FGFR2 and the FGFR3b and FGFR3c splice isoforms of FGFR3.3 FGF-9 is a high affinity, heparin dependent ligand for FGFR3 and FGFR2 but not for FGFR1 and FGFR4.4
