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.

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.

Alternatively spliced transcript variants encoding different isoforms have been identified.
