A potassium current activated by influx of Ca2+ into presynaptic terminals has been found in mouse motor endings. Its detection is greatly aided by blocking delayed rectifier K+ channels by 3,4-diaminopyridine (DAP). Ca2+-activated K+ current was readily abolished by tetraethylammonium (TEA) and by procedures which interfere with Ca2+ current.
