Résumé
Animal species representative of major phyla were found to contain activating factors similar to the Ca++ binding protein activator of 3′:5′ - cyclic nucleotide phosphodiesterase isolated from bovine heart. These factors are heat stable, non-dialysable and susceptible to proteolysis. All activate bovine heart cyclic nucleotide phosphodiesterase to a comparable extent and all activations are Ca++ dependent and reversible. The results suggest a ubiquitous distribution and fundamental importance for this Ca++ binding protein.
