  • Target

    • FunctionMay mediate the intracellular trafficking of ceramide in a non-vesicular manner.
    • Tissue specificityWidely expressed.
    • Sequence similaritiesContains 1 PH domain.
      Contains 1 START domain.
    • DomainThe START domain recognizes ceramide and mediates the intermembrane transfer of ceramide.
      The PH domain targets the Golgi apparatus.
      The FFAT motif is required for interaction with VAPA and VAPB.
    • Post-translational
      Phosphorylation on Ser-132 decreases the affinity toward phosphatidylinositol 4-phosphate at Golgi membranes and reduces ceramide transfer activity.
    • Cellular localizationCytoplasm. Golgi apparatus. Endoplasmic reticulum. Preferentially localized to the Golgi apparatus.

    Anti-COL4A3BP antibody images

    • ICC/IF image of ab72536 stained DU145. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat 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 ab72536 at (5 µg/mL) overnight at +4°C. The secondary antibody (green) was DyLight® 488 Goat anti Rabbit  (96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
