Enables potassium:proton antiporter activity and sodium:proton antiporter activity. Involved in several processes, including monoatomic cation transmembrane transport; phagosome maturation; and regulation of intracellular pH. Located in early phagosome; phagocytic vesicle membrane; and plasma membrane. Is expressed in several structures, including ear; hemolymphoid system; nervous system; tail somite; and urinary system. Used to study autism spectrum disorder. Human ortholog(s) of this gene implicated in autistic disorder. Orthologous to human SLC9A9 (solute carrier family 9 member A9).
