Automated description from the Alliance of Genome Resources (Release 3.2)
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 modulation of chemical synaptic transmission. Localizes to several cellular components, including mitochondrial outer membrane; postsynaptic density; 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).
