The effects of cycloheximide on Na+/H+ antiporter activity in cultured opossum kidney cells

These studies examined the effects of cycloheximide on the Na+/H+ antiporter in cultured opossum kidney cells. The effects of cycloheximide on antiporter activity depended on the basal level of activity. These data suggest that the Na+/H+ antiporter may be regulated by several processes which are sensitive to protein synthesis inhibition.
