Mitochondrial porin and phospholipid scramblase; voltage-dependent anion channel in the outer mitochondrial membrane required for maintenance of mitochondrial osmotic stability and membrane permeability; scramblase involved in mitochondrial transbilayer translocation of phospholipids; ubiquinone binding protein; couples glutathione pools of the intermembrane space and the cytosol; phosphorylated; protein abundance increases in response to DNA replication stress; orthologous to human VDAC1 and 2
