Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables calcium:sodium antiporter activity and monoatomic ion antiporter activity involved in regulation of postsynaptic membrane potential. Involved in several processes, including learning or memory; monoatomic cation transmembrane transport; and nervous system development. Acts upstream of or within several processes, including calcium ion transmembrane transport; hematopoietic progenitor cell differentiation; and modulation of chemical synaptic transmission. Located in 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).
