  • Form

  • Additional notes

    mFGF-9 is fully biologically active when compared to standards. The ED50, as determined by the dose-dependent stimulation of thymidine uptake by BaF3 expressing FGF receptors, is less than 0.5 ng/ml, corresponding to a specific activity of >2 X 106 units/mg. Murine FGF-9 exerts full activity on both murine and human cells. For most in vitro applications, FGF-9 exerts its biological activity in the concentration range of 0.1 to 20.0 ng/ml.

    Previously labelled as FGF9.

  • Function

    May have a role in glial cell growth and differentiation during development, gliosis during repair and regeneration of brain tissue after damage, differentiation and survival of neuronal cells, and growth stimulation of glial tumors.
  • Tissue specificity

    Glial cells.
  • Involvement in disease

    Defects in FGF9 are the cause of multiple synostoses syndrome type 3 (SYNS3) [MIM:612961]. Multiple synostoses syndrome is an autosomal dominant condition characterized by progressive joint fusions of the fingers, wrists, ankles and cervical spine, characteristic facies and progressive conductive deafness.
  • Sequence similarities

    Belongs to the heparin-binding growth factors family.
  • Post-translational

    Three molecular species were found (30 kDa, 29 kDa and 25 kDa), cleaved at Leu-4, Val-13 and Ser-34 respectively. The smaller ones might be products of proteolytic digestion. Furthermore, there may be a functional signal sequence in the 30 kDa species which is uncleavable in the secretion step.
  • Cellular localization
