Other IDs

• MIM: 601867
• HGNC: 806
• e!Ensembl: ENSG00000069849

Protein

• UniProt ID: P54709
• Protein name: Sodium/potassium-transporting ATPase subunit beta-3 (Sodium/potassium-dependent ATPase subunit beta-3) (ATPB-3) (CD antigen CD298)
• Protein function: This is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na(+) and K(+) ions across the plasma membrane. The exact function of the beta-3 subunit is not known.
