Protein DRA is a membrane protein in intestinal cells. It is an anion exchanger and a member of the sulfate anion transporter (SAT) family. It mediates chloride and bicarbonate exchange and additionally transports sulfate and other anions at the apical membrane, part of the plasma membrane of enterocytes. It is different from the anion exchanger that present in erythrocytes, renal tubule, and several other tissues. WebThe bicarbonate generated by carbonic anhydrase is excreted back into blood in exchange for chloride, via a chloride/bicarbonate exchanger (the energy for this exchanger is derived from the sodium/potassium pump located on the basolateral membrane.
