AT12A_HUMAN
Evidence for PS localization
Functions
The catalytic subunit of a H(+)/K(+) ATPase and/or Na(+)/K(+) ATPase pump which transports K(+) ions in exchange for Na(+) and/or H(+) ions across the apical membrane of epithelial cells. Uses ATP as an energy source to pump K(+) ions into the cell while transporting Na(+) and/or H(+) ions to the extracellular compartment (PubMed, PubMed, PubMed, PubMed). Involved in the maintenance of electrolyte homeostasis through K(+) ion absorption in kidney and colon . In the airway epithelium, may play a primary role in mucus acidification regulating its viscosity and clearance (PubMed). [View more on UniProt]
