    • Function

      A scaffold protein that connects plasma membrane proteins and regulatory components, regulating their surface expression in epithelial cells apical domains. May be involved in the coordination of a diverse range of regulatory processes for ion transport and second messenger cascades. In complex with SLC9A3R1, may cluster proteins that are functionally dependent in a mutual fashion and modulate the trafficking and the activity of the associated membrane proteins. May play a role in the cellular mechanisms associated with multidrug resistance through its interaction with ABCC2 and PDZK1IP1. May potentiate the CFTR chloride channel activity. May function to connect SCARB1 with the cellular machineries for intracellular cholesterol transport and/or metabolism. May be involved in the regulation of proximal tubular Na(+)-dependent inorganic phosphate cotransport therefore playing an important role in tubule function.
    • Tissue specificity

      Expression is limited to epithelial cells. Expressed in the kidney (brush border of proximal tubule), pancreas, liver, and small intestine. Expressed at a lower level in the adrenal cortex, testis and stomach. Overexpressed in breast, renal and lung carcinomas.
    • Sequence similarities

      Belongs to the NHER family.
      Contains 4 PDZ (DHR) domains.
    • Domain

      The PDZ 2 and 3 domains seem to be involved in the interaction with SLC26A3.
      Interaction with the C-terminus of CFTR could be mediated through independent binding of PDZ 1, 3 and 4 domains.
      The PDZ 1 and 3 domains seem to be involved in the interaction with SLCO1A1.
      The PDZ 1 domain interacts with BCR.
    • Cellular localization

      Cytoplasm. Membrane. Associated with peripheral membranes. Localizes to the apical compartment of proximal tubular cells and to sinusoidal liver membranes.
