Automated description from the Alliance of Genome Resources
Exhibits calcium:sodium antiporter activity involved in regulation of cardiac muscle cell membrane potential and protein homodimerization activity. Involved in cellular calcium ion homeostasis; regulation of lymphocyte chemotaxis; and sodium ion transmembrane transport. Localizes to the mitochondrion and plasma membrane. Is expressed in forelimb bud. Orthologous to human SLC8B1 (solute carrier family 8 member B1).
