Summary: Enables sodium,bicarbonate:chloride antiporter activity. Involved in regulation of synaptic vesicle exocytosis. Acts upstream of or within positive regulation of synaptic vesicle exocytosis and regulation of intracellular pH. Located in several cellular components, including basolateral plasma membrane; neuronal cell body membrane; and presynapse. Is active in glutamatergic synapse and presynaptic membrane. Is expressed in several structures, including adrenal gland; alimentary system; genitourinary system; nervous system; and sensory organ. Orthologous to human SLC4A8 (solute carrier family 4 member 8). [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.
