Recombinant Human Sodium/potassium-transporting ATPase subunit beta-2 (ATP1B2), Truncated

Uniprot Id

P14415

Target Species

Human

Target Name

ATP1B2

Target Full Name

Sodium/potassium-transporting ATPase subunit beta-2

Target Function

This is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na(+) and K(+) ions across the plasma membrane. The exact function of the beta-2 subunit is not known.; Mediates cell adhesion of neurons and astrocytes, and promotes neurite outgrowth.

Target Subcellular Location

Cell membrane; Single-pass type II membrane protein.

Target Protein Families

X(+)/potassium ATPases subunit beta family

Target Synonyms

ATP1B2; Sodium/potassium-transporting ATPase subunit beta-2; Adhesion molecule in glia; AMOG; Sodium/potassium-dependent ATPase subunit beta-2

Target Background

The protein encoded by this gene belongs to the family of Na+/K+ and H+/K+ ATPases beta chain proteins, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane. The glycoprotein subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes a beta 2 subunit. Two transcript variants encoding different isoforms have been found for this gene.
