Na+/K+-ATPase (also known as the Na+/K+ pump or sodium-potassium pump) is an enzyme located in the plasma membrane (specifically an electrogenic transmembrane ATPase). It is found in the plasma membrane of virtually every human cell and is common to all cellular life. It helps maintain cell potential and regulate cellular volume. In order to maintain the cell potential, cells must keep a low concentration of sodium ions and high levels of potassium ions within the cell (intracellular). Outside cells (extracellular), there are high concentrations of sodium and low concentrations of potassium, so diffusion occurs through ion channels in the plasma membrane. In order to keep the appropriate concentrations, the sodium-potassium pump pumps sodium out and potassium in through active transport.
Alpha 1 mRNA is present in all cell types examined.

1. Do not boil microsomes. Warming to 37ºC for 15 minutes is recommended. 2. Microsomes from some tissues may contain sodium pump subunits which are below the level of detection by this antibody. 3. Microsomes derived from tissues which are more difficult to prepare, such as smooth and skeletal muscle, frequently show non-specific cross-reactivity.

This antibody recognizes the α-1 subunit isoform of Na+/K+ ATPase.
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.
FUNCTION: SwissProt: P13637 # 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. SIZE: 1013 amino acids; 111749 Da SUBUNIT: Composed of three subunits: alpha (catalytic), beta and gamma. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. DISEASE: SwissProt: P13637 # Defects in ATP1A3 are the cause of dystonia-12 (DYT12) [MIM:128235]; also known as rapid-onset dystonia parkinsonism (RDP). DYT12 is an autosomal dominant form of dystonia- parkinsonism characterized by an unusually rapid evolution of signs and symptoms. Affected persons develop dystonia and parkinsonism between 14 and 45 years of age. The sudden onset of symptoms over hours to a few weeks, often associated with physical or emotional stress, suggests a trigger initiating a nervous system insult resulting in permanent neurologic disability. SIMILARITY: SwissProt: P13637 ## Belongs to the cation transport ATPase (P-type) family. Type IIC subfamily.
