Exhibits sodium channel regulator activity. Involved in positive regulation of sodium ion export across plasma membrane; regulation of cardiac muscle cell membrane potential; and regulation of sodium ion transmembrane transporter activity. Localizes to the sarcolemma. Is expressed in several structures, including central nervous system; genitourinary system; heart; liver; and lung. Orthologous to human FXYD1 (FXYD domain containing ion transport regulator 1).
