The gating process of VDAC consisting of one open state and two closed states: one of these achieved at positive potentials and the other at negative potentials. The black region is the positively-charged, mobile, voltage-sensor domain. Its movement out of the channel results in a reduced diameter, reduced volume, and inverted ion selectivity. Each closed state is actually a population of closed states.
