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.
Detected in liver, kidney, pancreas, prostate, spleen, small intestine and placenta, in particular in the syncytiotrophoblast.
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).
Contains 2 PDZ (DHR) domains.
Phosphorylated on serine residues.
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.

Western blot - Anti-EBP50 antibody [EPR5562] (ab109430)
Predicted band size : 39 kDa
Lane 1: Wild-type HAP1 cell lysate (20 µg) Lane 2: EBP50 knockout HAP1 cell lysate (20 µg) Lane 3: Jurkat cell lysate (20 µg) Lane 4: HepG2 cell lysate (20 µg) Lanes 1 - 4: Merged signal (red and green). Green - ab109430 observed at 48 kDa. Red - loading control, ab18058, observed at 124 kDa.
ab109430 was shown to recognize EBP50 when EBP50 knockout samples were used, along with additional cross-reactive bands. Wild-type and EBP50 knockout samples were subjected to SDS-PAGE. ab109430 and ab18058 (loading control to Vinculin) were diluted at 1/500 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed withGoat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
