Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
