  • Function
    Receptor for Wnt proteins. Component of the Wnt-Fzd-LRP5-LRP6 complex that triggers beta-catenin signaling through inducing aggregation of receptor-ligand complexes into ribosome-sized signalosomes. The beta-catenin canonical signaling pathway leads to the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. May be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues. Coreceptor along with RYK of Wnt proteins, such as WNT1.
  • Tissue specificity
    Most abundant in fetal kidney, followed by brain and lung. In adult tissues, expressed in kidney, heart, pancreas and skeletal muscle.
  • Sequence similarities
    Belongs to the G-protein coupled receptor Fz/Smo family.
    Contains 1 FZ (frizzled) domain.
  • Domain
    The PDZ-binding motif mediates interaction with GOPC.
    Lys-Thr-X-X-X-Trp motif interacts with the PDZ doman of Dvl (Disheveled) family members and is involved in the activation of the Wnt/beta-catenin signaling pathway.
    The FZ domain is involved in binding with Wnt ligands.
  • Post-translational
    Ubiquitinated by ZNRF3, leading to its degradation by the proteasome.
  • Cellular localization
    Membrane. Golgi apparatus. Cell membrane. Colocalizes with GOPC at the Golgi apparatus.

Anti-Frizzled 8 antibody images

  • ICC/IF image of ab40012 stained Hek293 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab40012 at 10µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 donkey anti- goat (ab150133) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

  • Anti-Frizzled 8 antibody (ab40012) at 1 µg/ml + Human Pancreas lysate in RIPA buffer at 35 µg

    Predicted band size : 73 kDa
    Observed band size : 75 kDa (why is the actual band size different from the predicted?)
    Primary incubation was 1 hour. Detected by chemiluminescence.
