== Function ==
[https://www.uniprot.org/uniprot/VDAC1_HUMAN VDAC1_HUMAN] Forms a channel through the mitochondrial outer membrane and also the plasma membrane. The channel at the outer mitochondrial membrane allows diffusion of small hydrophilic molecules; in the plasma membrane it is involved in cell volume regulation and apoptosis. It adopts an open conformation at low or zero membrane potential and a closed conformation at potentials above 30-40 mV. The open state has a weak anion selectivity whereas the closed state is cation-selective. May participate in the formation of the permeability transition pore complex (PTPC) responsible for the release of mitochondrial products that triggers apoptosis.<ref>PMID:11845315</ref> <ref>PMID:15033708</ref> <ref>PMID:18755977</ref>

== Publication Abstract from PubMed ==
15 N spin-relaxation rates are demonstrated to provide critical information about the long-range structure and internal motions of membrane proteins. Combined with an improved calculation method, the relaxation-rate-derived structure of the 283-residue human voltage-dependent anion channel revealed an anisotropically shaped barrel with a rigidly attached N-terminal helix. Our study thus establishes an NMR spectroscopic approach to determine the structure and dynamics of mammalian membrane proteins at high accuracy and resolution.
