General FunctionSodium:potassium-exchanging atpase activity
Specific FunctionThis 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-2 subunit is not known.Mediates cell adhesion of neurons and astrocytes, and promotes neurite outgrowth.
