The sodium/potassium ATPase is an integral membrane enzyme found in all cells of higher organisms and is responsible for the ATP dependent transport of sodium and potassium across the cell membrane. This membrane bound enzyme is related to a number of other ATPases including sarcoplasmic and endoplasmic reticulum calcium ATPase (SERCA) and plasma membrane calcium ATPase (PMCA). The enzyme consists of an a and b subunit, both of which exist as isoforms. The a subunit is believed to be the catalytically active subunit, while the b subunit appears necessary for the assembly and transport of the sodium pump to the plasma membrane. The beta subunit is a membrane spanning glycoprotein present in all cell types. The sodium/potassium ATPase consists of a large, multipass, transmembrane catalytic subunit, termed the alpha subunit, and an associated smaller glycoprotein, termed the beta subunit. Studies indicate that there are three isoforms of the alpha subunit (alpha 1, alpha 2, alpha 3) and two isoforms of the beta subunit (beta 1 and beta 2) encoded by two multigene families. The different isoforms of the sodium/potassium ATPase exhibit a tissue-specific and developmental pattern of expression. The alpha 1 and beta mRNAs are present in all cell types examined whereas the alpha 2 and alpha 3 mRNAs exhibit a more restricted pattern of cell-specific expression.Synonyms: Sodium Pump ATPase subunit beta-1, Sodium/potassium-dependent ATPase subunit beta-1, Sodium/potassium-transporting ATPase subunit beta-1
