An ATPase has been found in association with cell membranes. The enzyme is stimulated by sodium and inhibited by cardiac glycosides (ouabain and digitalis). If potassium is present, the stimulation by sodium is enhanced. The enzyme originally described in crab nerve and erythrocyte ghost was later found in a number of tissues— kidney, ciliary body, brain, giant axon, ascites cell, skin cell, lens, leukocyte, and skeletal and heart muscle.
