motifs/domains
  • an N-terminal signal peptide
  • two Asn-linked glycosylation sites within the N-terminal extracellular region
  • lys-thr-X-X-X-thr motif involved in the activation of the WNT/beta-catenin signaling pathway
  • a fz domain involved in binding with WNT ligands
  • a CRD
  • seven transmenbrane domains
  • three N-linked glycosylation sites
  • a C-terminal ser/thr-X-val motif which is a binding site for scaffold proteins with multiple PDZ domains
  • conjugated GlycoP

    text
  • multi-pass membrane protein
  • basic FUNCTION
  • acting as a receptor for WNT proteins
  • coupled to the beta-catenin canonical signaling pathway, leading to the activation of dishvelled proteins, inhibition of GSK3 kinase, nuclear accumulation of beta-catenin and activation of WNT target genes
  • playing a role in several types of human cancer through activation of the beta-catenin-TCF pathway
  • may be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues
  • may be functionally important for aberrant activation of the canonical Wnt signaling pathway in human lung cancer cells
  • may play an important role in aberrant activation of the canonical Wnt pathway which is critical for the proliferation and survival of lung cancer cells
  • FZD5 and FZD8 are involved in dose-dependent regulation of signaling in optic fissure/disc formation and progenitor expansion

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • WNT receptor
  • scaffold proteins with multiple PDZ domains
  • interacting with GOPC
  • interacting with RSPO1 and RSPO3
  • binding to IGFBP4
  • IGFBP4 physically interacted with FZD8, and a Wnt co-receptor, LRP6, and inhibited the binding of WNT3A to FZD8 and LRP6
  • interacting with INVS (INVS is essential for the morphogenesis of the proximal and intermediate pronephric system and relays Frizzled-8–dependent signals to recruit Dishevelled to the plasma membrane)
