1 These currents, which were activated by 1-s voltage pulses of -100 mV (vacuolar interior negative) in the presence of 100 muM Ca(2+) (cytosolic side), could be blocked completely and reversibly by the calmodulin antagonist W-7 [N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide] and its chlorine-deficient analogue W-5; half-maximum inhibition was found at approx. N-(6-aminohexyl)-1-naphthalenesulfonamide calmodulin Bos taurus
