COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staff. The
            reference sequence was derived from AK309734.1, EU934248.1,
            EU934249.1, FJ178574.1, EU499349.1, AK310865.1, AF053755.1,
            AF047033.1, AL389947.1 and AA569234.1.
            This sequence is a reference standard in the RefSeqGene project.

            Summary: This locus encodes a sodium bicarbonate cotransporter. The
            encoded transmembrane protein appears to transport sodium and
            bicarbonate ions in a 1:1 ratio, and is thus considered an
            electroneutral cotransporter. The encoded protein likely plays a
            critical role in regulation of intracellular pH involved in visual
            and auditory sensory transmission. Alternatively spliced transcript
            variants encoding distinct isoforms have been described. [provided
