Protein Information (annotations from UniProt)

Database IDHIV0003272
UniProt IDP21796
Primary gene name(s)VDAC1
Synonym gene name(s)VDAC
Protein nameVoltage-dependent anion-selective channel protein 1
Protein functionForms 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, PubMed:11845315, PubMed:18755977, PubMed:20230784, PubMed:8420959. May participate in the formation of the permeability transition pore complex, PTPC responsible for the release of mitochondrial products that triggers apoptosis, PubMed:15033708, PubMed:25296756. {ECO:0000269|PubMed:11845315, ECO:0000269|PubMed:15033708, ECO:0000269|PubMed:18755977, ECO:0000269|PubMed:20230784, ECO:0000269|PubMed:25296756, ECO:0000269|PubMed:8420959}.
