Automated description from the Alliance of Genome Resources
Exhibits calcium:sodium antiporter activity and ion antiporter activity involved in regulation of postsynaptic membrane potential. Involved in several processes, including inorganic cation transmembrane transport; learning or memory; and nervous system development. Localizes to several cellular components, including the mitochondrial outer membrane; neuromuscular junction; and sarcolemma. Is expressed in several structures, including bone; brain; foregut; genitourinary system; and trachea. Orthologous to human SLC8A3 (solute carrier family 8 member A3).
