Voltage-gated anion-selective channel VDAC

Solutes enter mitochondria through pores in thousands of molecules of the voltage-gated anion-selective channel VDAC, also known as mitochondrial porin.1516 288 289 In the absence of a membrane potential these pores allow free diffusion to molecules up to 1.2 kDa in mass and may selectively permit passage of anions of 3- to 5-kDa mass. However, a membrane potential greater than 20 mV causes the pores to close. NADH also decreases permeability.
