Solute carrier family 26 member 6 is a protein that in humans is encoded by the SLC26A6 gene.[5][6][7] It is an anion-exchanger expressed in the apical membrane of the kidney proximal tubule, the apical membranes of the duct cells in the pancreas, and the villi of the duodenum.[8]
This gene belongs to the solute carrier 26 family, whose members encode anion transporter proteins. This particular family member encodes a protein involved in transporting chloride, oxalate, sulfate and bicarbonate. Several alternatively spliced transcript variants of this gene, encoding distinct isoforms, have been described, but the full-length nature of some of these variants has not been determined.[7]
