  • Function
    Scaffold protein that connects plasma membrane proteins with members of the ezrin/moesin/radixin family and thereby helps to link them to the actin cytoskeleton and to regulate their surface expression. Necessary for recycling of internalized ADRB2. Was first known to play a role in the regulation of the activity and subcellular location of SLC9A3. Necessary for cAMP-mediated phosphorylation and inhibition of SLC9A3. May enhance Wnt signaling. May participate in HTR4 targeting to microvilli (By similarity). Interacts with MCC.
  • Tissue specificity
    Detected in liver, kidney, pancreas, prostate, spleen, small intestine and placenta, in particular in the syncytiotrophoblast.
  • Involvement in disease
    Defects in SLC9A3R1 are the cause of hypophosphatemic nephrolithiasis/osteoporosis type 2 (NPHLOP2) [MIM:612287]. Hypophosphatemia results from idiopathic renal phosphate loss. It contributes to the pathogenesis of hypophosphatemic urolithiasis (formation of urinary calculi) as well to that of hypophosphatemic osteoporosis (bone demineralization).
  • Sequence similarities
    Contains 2 PDZ (DHR) domains.
  • Post-translational
    Phosphorylated on serine residues.
  • Cellular localization
    Cytoplasm. Apical cell membrane. Endomembrane system. Cell projection > filopodium. Cell projection > ruffle. Cell projection > microvillus. Translocates from the cytoplasm to the apical cell membrane in a PODXL-dependent manner (By similarity). Colocalizes with actin in microvilli-rich apical regions of the syncytiotrophoblast. Found in microvilli, ruffling membrane and filopodia of HeLa cells. Present in lipid rafts of T-cells.

  • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: EBP50 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: Jurkat whole cell lysate (20 µg)
    Lane 4: HepG2 whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab88238 observed at 48 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab88238 was shown to specifically react with EBP50 in wild type cells as signal was lost in EBP50 knockout cells. Wild-type and EBP50 knockout samples were subjected to SDS-PAGE. ab88238 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1 µg/ml and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
