Predicted to enable chloride transmembrane transporter activity and sodium:bicarbonate symporter activity. Predicted to be involved in bicarbonate transport; inorganic ion transmembrane transport; and regulation of intracellular pH. Predicted to act upstream of or within positive regulation of synaptic vesicle exocytosis and regulation of membrane potential. Located in several cellular components, including axon; glutamatergic synapse; and synaptic vesicle. Biomarker of prediabetes syndrome. Orthologous to human SLC4A8 (solute carrier family 4 member 8).
