The Ca2+ uptake of the mitochondria of guinea pig peritoneal macrophages was not stimulated by the addition of calmodulin. However, calmodulin antagonists, both phenotiazines and N-naphthalenesulfonamides, in low concentrations inhibited the Ca2+ uptake of the mitochondoria, as compared to the inhibition of the calmodulin-dependent stimulation of brain phosphodiesterase. These calmodulin antagonists appear to have severe side effects on active processes of the mitochondria and which are unrelated to the specific effect on calmodulin.
