    text
  • is a ciliary protein and is preferentially localized at the base and tip of cilia
  • basic FUNCTION
  • is a key regulator of hedgehog signaling and an intraflagellar transport B complex protei
  • CLUAP1 contributes to ciliogenesis by regulating the intraflagellar transport (IFT) cycle at the base and tip of the cilium
  • is essential for ciliogenesis and photoreceptor maintenance in the vertebrate eye
  • required for ciliogenesis and cilia maintenance

  • intraflagellar transport proteins IFT172, IFT80, IFT57, TRAF3IP1, CLUAP1, and IFT20 form a stable tubulin-binding IFT-B2 complex

    Candidate gene
  • CLUAP1 is a candidate Leber congenital amaurosis (LCA) gene
  • Marker
    Therapy target
  • may conceivably serve in the future as a novel therapeutic intervention for treatment of colon cancer
  • useful as a prognostic/diagnostic marker and/or for a target of immunotherapy of osteosarcoma
  • ANIMAL & CELL MODELS
  • Cluap1-/- embryos died mid-gestation manifesting impairment of ciliogenesis in various regions including the node and neural tube
