    basic FUNCTION
  • autocrine/paracrine growth factor, playing an important for glial cell development
  • playing a role in retinal differentiation and maturation, possibly representing a neuronally derived factor acting upon glial (and other) cells
  • mesothelial and epithelial FGF9 directs lung development by regulating mesenchymal growth, and the pattern and expression levels of mesenchymal growth factors that signal back to the epithelium
  • playing a role in XY germ cell survival
  • perichondrial FGF1, FGF2, FGF6, FGF7, FGF9, FGF18, FGF21, FGF22 regulate growth plate chondrogenesis
  • plays a role in colorectal and endometrial carcinogenesis
  • playing an important role in normal joint development
  • homodimerization controls the binding to the receptor and heparan sulfate dependent diffusion in the extracellular matrix
  • might be important during various stages of bone healing
  • contributes functionally to both angiogenic and osteogenic processes during bone repair
  • required for lung development
  • CELLULAR PROCESS cell life, proliferation/growth
    cell life, antiapoptosis
    nucleotide, transcription
    PHYSIOLOGICAL PROCESS endocytosis transport
    PATHWAY
    metabolism
    signaling
  • TGFB1-FGF9-PITX2 signaling cascade regulates cranial neural crest cell proliferation during palate formation
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • cooperate with SHH to regulate mesenchymal proliferation in distinct submesothelial and subepithelial regions
  • FUBP3 regulates FGF9 expression at the post-transcriptional level
  • interaction between FUBP3 and FGF9 3prime-UTR UG-repeat promoting FGF9 mRNA translation
  • cell & other

    ANIMAL & CELL MODELS
  • spontaneous dominant mouse mutant, Elbow knee synostosis (Eks), shows elbow and knee joint synosostis, and premature fusion of cranial sutures
  • loss of Fgf9 in XX Wnt4(-/-) gonads does not rescue their partial female-to-male sex-reversal
  • embryos lacking Fgf9 show mesenchymal hypoplasia, decreased epithelial branching and, by the end of gestation, hypoplastic lungs that cannot support life
