+== Function ==
+[https://www.uniprot.org/uniprot/ATP4A_PIG ATP4A_PIG] Catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. Responsible for acid production in the stomach.

+== Publication Abstract from PubMed ==
+The gastric proton pump-the H(+), K(+)-ATPase-is a P-type ATPase responsible for acidifying the gastric juice down to pH 1. This corresponds to a million-fold proton gradient across the membrane of the parietal cell, the steepest known cation gradient of any mammalian tissue. The H(+), K(+)-ATPase is an important target for drugs that treat gastric acid-related diseases. Here we present crystal structures of the H(+), K(+)-ATPase in complex with two blockers, vonoprazan and SCH28080, in the luminal-open state, at 2.8 A resolution. The drugs have partially overlapping but clearly distinct binding modes in the middle of a conduit running from the gastric lumen to the cation-binding site. The crystal structures suggest that the tight configuration at the cation-binding site lowers the pK a value of Glu820 sufficiently to enable the release of a proton even into the pH 1 environment of the stomach.
