nrv2

Gene
nrv2
Protein
Sodium/potassium-transporting ATPase subunit beta-2
Organism
Drosophila melanogaster
Length
323 amino acids
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.
Similarity
Belongs to the X(+)/potassium ATPases subunit beta family.
Mass
