Predicted to enable potassium:proton antiporter activity and sodium:proton antiporter activity. Predicted to be involved in potassium ion transmembrane transport; regulation of Golgi lumen acidification; and sodium ion import across plasma membrane. Predicted to act upstream of or within potassium ion transport. Predicted to be located in recycling endosome membrane and trans-Golgi network. Predicted to be integral component of membrane. Predicted to be active in plasma membrane and recycling endosome. Human ortholog(s) of this gene implicated in X-linked intellectual developmental disorder 108. Orthologous to human SLC9A7 (solute carrier family 9 member A7). [provided by Alliance of Genome Resources, Apr 2022]
