Introduction: we have recently reported the presence of two potassium currents with 598 and 368 pS conductance
in the rough endoplasmic reticulum (RER) membrane. The 598 pS channel was voltage dependent and ATP sensitive.
However, the 368 pS channel was rarely observed and its identity remained obscure. Since cationic channels in
intracellular organelles such as mitochondria and RER play imp...
