VDAC3: Proteins and Enzymes

The Voltage-Dependant Anion Channel (VDAC3) of the outer mitochondrial membrane, a small abundant protein found in all eukaryotic kingdoms, forms a voltage-gated pore when incorporated into planar lipid bilayers. VDAC is also the site of binding of the metabolic enzymes hexokinase and glycerol kinase to the mitochondrion in what may be a significant metabolic regulatory interaction. VDAC3 is involved specifically in translocation of adenine nucleotides through the outer membrane.
