The protein encoded by this gene belongs to a family of P-type cation-transporting ATPases. The gastric H+, K+-ATPase is a heterodimer consisting of a high molecular weight catalytic alpha subunit and a smaller but heavily glycosylated beta subunit. This enzyme is a proton pump that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for gastric acid secretion. This gene encodes the beta subunit of the gastric H+, K+-ATPase.

Interaction
The ATPase pump is composed of two subunits: alpha (catalytic) and beta (regulatory). Interacts with alpha subunit ATP12A; this interaction is required for the formation of a functionally active pump and targeting at the plasma membrane (By similarity). Interacts (via N-terminus) with alpha subunit ATP4A (via the P-domain) (By similarity).
