Atp1b2 Gene Summary [Rat]
Enables P-type sodium:potassium-exchanging transporter activity and protein heterodimerization activity. Predicted to be involved in several processes, including intracellular monoatomic cation homeostasis; monoatomic cation transmembrane transport; and positive regulation of cation transmembrane transport. Predicted to act upstream of or within several processes, including brain development; motor behavior; and photoreceptor cell maintenance. Located in apical plasma membrane. Part of sodium:potassium-exchanging ATPase complex. Orthologous to human ATP1B2 (ATPase Na+/K+ transporting subunit beta 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Atp1b2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
