Gene Symbol ATP1B1
Protein Name ATPase, Na+/K+ transporting, beta 1 polypeptide
Synonyms ATP1B;
Species Homo sapiens
Ensembl Protein ENSP00000356789
InnateDB Gene IDBG-104639 (ATP1B1)
Protein Structure
UniProt Annotation
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 beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane. {ECO:0000269PubMed:19694409}.Involved in cell adhesion and establishing epithelial cell polarity. {ECO:0000269PubMed:19694409}.
Subcellular Localization Cell membrane; Single-pass type II membrane protein.
Disease Associations
