Recombinant Human Sodium/potassium-transporting ATPase subunit alpha-3 (ATP1A3), Truncated

Uniprot Id

P13637

Target Species

Human

Target Name

ATP1A3

Target Full Name

Sodium/potassium-transporting ATPase subunit alpha-3

Target Function

This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium ions, providing the energy for active transport of various nutrients.

Target Involvement

Dystonia 12 (DYT12); Alternating hemiplegia of childhood 2 (AHC2); Cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss (CAPOS)

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

Cation transport ATPase (P-type) (TC 3.A.3) family, Type IIC subfamily

Target Background

The protein encoded by this gene belongs to the family of P-type cation transport ATPases, 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 catalytic subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes an alpha 3 subunit. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
