Predicted to enable several functions, including ATPase activator activity; ATPase binding activity; and P-type sodium:potassium-exchanging transporter activity. Predicted to be involved in several processes, including cellular monovalent inorganic cation homeostasis; ion transmembrane transport; and positive regulation of cation transmembrane transport. Predicted to act upstream of or within ion transport. Located in cytoplasm. Is expressed in several structures, including early conceptus; heart; hemolymphoid system; nervous system; and sensory organ. Orthologous to human ATP1B3 (ATPase Na+/K+ transporting subunit beta 3).
