  • a N terminal cysteine-rich domain
  • a conserved extracellular cysteine rich domain for ligand binding
  • seven transmembrane segments (7TM)

  • G-protein coupled receptor FZ/SMO family
  • CATEGORY receptor
    SUBCELLULAR LOCALIZATION     plasma membrane
  • after internalization, it appears that FZD5 is recycled back to the plasma membrane
  • basic FUNCTION
  • exhibiting characteristics of a WNT receptor
  • involved in signal transduction
  • may be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues
  • WNT5A and its receptor Frizzled-5 regulate inflammatory responses of human mononuclear cells induced by microbial stimulation
  • functioning as WNT5A receptor, and key molecule in the fields of oncology
  • central role for FZD5 signaling in mammalian eye development and are likely to be relevant to the etiology of congenital human ocular anomalies
  • mediates the synaptogenic effect of WNT7A and its localization to synapses is regulated by neuronal activity, a process that depends on endogenous Wnts
  • FZD5 and FZD8 are involved in dose-dependent regulation of signaling in optic fissure/disc formation and progenitor expansion
  • GCM1 and FZD5 function in an evolutionary conserved positive feedback loop that regulates trophoblast differentiation and sites of chorionic branching morphogenesis
  • potential role of FZD5 in neuronal polarization
  • has a role in the establishment of neuronal polarity, and in the morphogenesis of neuronal processes, in part through the activation of the non-canonical Wnt mechanism involving JNK
  • conserved role of Wnt-Frizzled (FZD) signaling in ocular development and directly implicate WNT-FZD signaling both in normal closure of the optic fissure and pathogenesis of coloboma
    signaling signal transduction
  • WNT5AFZD5 signaling in macrophages promotes phagocytosis through lipid raft clustering concomitant with RAC1PI3 kinaseIKB kinase activation
  • a component
    small molecule
  • activating Dishevelled
  • receptor for the WNT5A ligand (to induce the beta- catenin pathway)
  • binding to WNT7A (to activate -catenin/canonical signaling and induce proliferation in endometrial cancer cells)
  • SCYL2 regulates the amount of FZD5 by inducing lysosomal degradation, which probably contributes to the suppression of the Wnt signaling pathway
  • ability of WNT5AFZD5 signaling to stimulate phagocytosis of E. coli but not its killing makes it a likely mediator of uncontrolled inflammation or sepsis during infection
  • receptor for the synaptic organizer WNT7A, regulating activity-mediated synaptogenesis
  • LGR5 interacts and forms a supercomplex with the Wnt coreceptors LRP6 and FZD5 which is rapidly internalized and then degraded
  • WNT5A may exert its stimulatory effects on macrophages through autocrine and/or paracrine modes upon binding to the FZD5 receptor
  • monocyte-secreted WNT5A interacts with FZD5 in microvascular endothelial cells and induces angiogenesis through tissue factor signaling
