Summary: Predicted to enable ATPase activator activity and P-type potassium:proton transporter activity. Predicted to contribute to heterocyclic compound binding activity. Predicted to be involved in cellular monovalent inorganic cation homeostasis and inorganic cation transmembrane transport. Predicted to act upstream of or within pH reduction; protein glycosylation in endoplasmic reticulum; and regulation of proton transport. Predicted to be located in endoplasmic reticulum and plasma membrane. Predicted to be part of sodium:potassium-exchanging ATPase complex. Is expressed in alimentary system; stomach; stomach epithelium; stomach fundus; and stomach mucosa. Human ortholog(s) of this gene implicated in atrophic gastritis; autoimmune gastritis; and stomach cancer. Orthologous to human ATP4B (ATPase H+/K+ transporting subunit beta).

These results may imply that the H(+),K(+)-ATPase in the cochlear lateral wall is crucial for K(+) circulation and thus plays a critical role in generation of endocochlear potential.
Title: Gastric type H+,K+-ATPase in the cochlear lateral wall is critically involved in formation of the endocochlear potential.

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.
