Protein
Sodium/potassium-transporting ATPase subunit beta-1
Organism
Caenorhabditis elegans
Function
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 (By similarity). May also may function in the peptidic vesicle transport pathway from the endoplasmic reticulum for the defecation behaviors.
Similarity
Belongs to the X(+)/potassium ATPases subunit beta family.
