[5][6][7][8] The protein encoded by this gene belongs to the family of P-type cation transport ATPases.

This gene encodes a catalytic subunit of the ouabain-sensitive H+/K+ -ATPase that catalyzes the hydrolysis of ATP coupled with the exchange of H+ and K+ ions across the plasma membrane.

It is also responsible for potassium absorption in various tissues.
