title: Slowly-activating cation channels in the vacuolar membrane of plants.
abstract: Among other ion channels and transport proteins, the membrane of plant vacuoles contains a voltage- and calcium-dependent cation channel with activation kinetics in the range of seconds. This SV(= slow vacuolar)-channel has a unit conductance of 60 to 80 pS (in symmetrical 100 mM cation solution) and is strictly inward rectifying. Investigations on the pharmacology of this protein revealed reasonable similarities to calcium-dependent potassium channels of large conductance.
