Solute-linked carrier 26 (SLC26) isoforms are members of a large, conserved family of anion exchangers, many of which display highly restricted and distinct tissue distribution. Cloning experiments have identified 10 SLC26 genes or isoforms (SLC26A1-11). Except for SLC26A5 (prestin), all function as anion exchangers with versatility with respect to transported anions. Modes of transport mediate...
An outcome of overloading of the endoplasmic reticulum (ER) folding machinery is a perturbation in ER function and the formation of intracellular aggregates. The latter is a key pathogenic factor in numerous diseases known as ER storage diseases. Here, we report that heterologous overexpression of the green fluorescent protein-tagged iodide transporter pendrin (GFP-PDS) perturbs folding and deg...
Inactivation of the B1 proton pump subunit (ATP6V1B1) in intercalated cells (ICs) leads to type I distal renal tubular acidosis (dRTA), a disease associated with salt- and potassium-losing nephropathy. Here we show that mice deficient in ATP6V1B1 (Atp6v1b1-/- mice) displayed renal loss of NaCl, K+, and water, causing hypovolemia, hypokalemia, and polyuria. We demonstrated that NaCl loss origina...
Specialized epithelial cells in the amphibian skin play important roles in ion transport, but how they arise developmentally is largely unknown. Here we show that proton-secreting cells (PSCs) differentiate in the X. laevis larval skin soon after gastrulation, based on the expression of a `kidney-specific' form of the H(+)v-ATPase that localizes to the plasma membrane, orthologs of the Cl(-)/HC...
Since nitric oxide (NO) participates in the renal regulation of blood pressure, in part, by modulating transport of Na⁺ and Cl⁻ in the kidney, we asked whether NO regulates net Cl⁻ flux (JCl) in the cortical collecting duct (CCD) and determined the transporter(s) that mediate NO-sensitive Cl⁻ absorption. Cl⁻ absorption was measured in CCDs perfused in vitro that were taken from aldosterone-trea...
