Summary: Enables chloride channel activity and chloride:bicarbonate antiporter activity. Involved in several processes, including bicarbonate transport; carboxylic acid transport; and inorganic anion transmembrane transport. Acts upstream of or within chloride transport. Located in basolateral plasma membrane. Is expressed in several structures, including alimentary system; brain; limb; respiratory system; and sensory organ. Used to study congenital hypothyroidism. Orthologous to human SLC26A7 (solute carrier family 26 member 7). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
