ATPase, Na+/K+ transporting, alpha 2 (+) polypeptide, also known as ATP1A2, is a protein which in humans is encoded by the ATP1A2 gene.

Contents

Function

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 2 subunit.

Clinical significance

Mutations in the ATP1A2 gene has been implicated in the familial form of alternating hemiplegia of childhood.
