Text
  • brain, developing neural tube
  • found in the growth cones of adult spiral ganglion neurons
  • PROTEIN
    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • receptor consisting of a N terminal cysteine-rich domain, seven transmembrane segments (7TM)
  • one FZD domain for ligand binding
  • a C terminal hydrophilic segment,comprising the S/T-X-X-X-W motif
  • HOMOLOGY
    interspecies homolog to Drosophila frizzled polarity gene

    basic FUNCTION
  • activating Dishevelled
  • exhibiting characteristics of a WNT receptor
  • critical determinant of hippocampal development and is very likely to be a contributing factor to the neurodevelopmental and behavioral phenotype of patients with Williams syndrome
  • receptor of Wnt ligands, playing key roles in liver carcinogenesis
  • having a function in osteoblasts, a finding that may have therapeutic implications for bone loss disorders (

    protein
  • WNT2 could act through its receptor FZD9 to regulate the CTNNB pathway in cumulus cells, recruiting CTNNB into plasma membranes and promoting the formation of adherens junctions involving CDH1

    FZD9-siRNA could represent a useful therapeutic target for hepatocellular carcinoma (HCC) and hepatoblastoma (HB)
    ANIMAL & CELL MODELS
  • Fzd9(-/-) mice display low bone mass caused by impaired bone formation
  • Frizzled 9-null mice had generally normal gross anatomical hippocampal organization but showed large increases in apoptotic cell death in the developing dentate gyrus
