Summary: Predicted to enable P-type potassium transmembrane transporter activity and metal ion binding activity. Predicted to be involved in intracellular monoatomic cation homeostasis and monoatomic cation transmembrane transport. Predicted to act upstream of or within pH reduction; regulation of proton transport; and response to xenobiotic stimulus. Located in apical plasma membrane. Orthologous to human ATP4A (ATPase H+/K+ transporting subunit alpha). [provided by Alliance of Genome Resources, Dec 2024]

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.
