Non-selective voltage-gated ion channel that mediates the transport of anions and cations through the mitochondrion outer membrane and plasma membrane (PubMed:10661876, PubMed:11845315, PubMed:18755977, PubMed:30061676, PubMed:8420959). 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 (PubMed:10661876, PubMed:11845315, PubMed:18755977, PubMed:8420959). It adopts an open conformation at low or zero membrane potential and a closed conformation at potentials above 30-40 mV (PubMed:10661876, PubMed:18755977, PubMed:8420959). The open state has a weak anion selectivity whereas the closed state is cation-selective (PubMed:18755977, PubMed:8420959). Binds various signaling molecules, including the sphingolipid ceramide, the phospholipid phosphatidylcholine, and the sterols cholesterol and oxysterol (PubMed:18755977, PubMed:31015432). In depolarized mitochondria, acts downstream of PRKN and PINK1 to promote mitophagy or prevent apoptosis; polyubiquitination by PRKN promotes mitophagy, while monoubiquitination by PRKN decreases mitochondrial calcium influx which ultimately inhibits apoptosis (PubMed:32047033). 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). May mediate ATP export from cells (PubMed:30061676). Part of a complex composed of HSPA9, ITPR1 and VDAC1 that regulates mitochondrial calcium-dependent apoptosis by facilitating calcium transport from the ER lumen to the mitochondria intermembrane space thus providing calcium for the downstream calcium channel MCU that directly releases it into mitochondria matrix (By similarity). Mediates cytochrome c efflux (PubMed:20230784). Catalyzes the scrambling of phospholipids across the outer mitochondrial membrane; the mechanism is unrelated to channel activity and is capable of translocating both anionic and zwitterionic phospholipids.

The VDAC1/Porin and VDAC2 proteins also known as voltage-dependent anion-selective channel 1 and 2 serve as important pore-forming proteins within the mitochondrial outer membrane. Each VDAC protein has a molecular mass of about 30-35 kDa. Commonly referred to as the 'porin hub' due to their central role in metabolite exchange VDAC1 and VDAC2 facilitate the transport of ions and small molecules between the mitochondria and cytoplasm regulating energy production and cellular metabolism. They express widely across various tissues highlighting their essential role in cellular functions.
Voltage-dependent anion channels like VDAC1/Porin and VDAC2 modulate the exchange of ions and metabolic substrates playing a significant role in apoptosis and the maintenance of mitochondrial functions. As integral parts of mitochondrial complexes they interact with proteins such as hexokinase which anchors to VDAC1 and influences glycolytic flux linking energy production with apoptotic signaling pathways. This positions VDAC proteins as key regulators of cellular energy homeostasis.
VDAC1/Porin and VDAC2 engage prominently in the apoptotic and mitochondrial permeability transition pathways. In the apoptosis pathway they interact with anti-apoptotic proteins like Bcl-xl and pro-apoptotic members like Bax highlighting their dual role in cell survival and death. These interactions highlight the proteins’ contribution to mitochondrial outer membrane permeabilization (MOMP) a critical event in the release of cytochrome c and subsequent apoptosome formation further integrating them into broader signaling networks.
Dysfunctions in VDAC1/Porin and VDAC2 link to neurodegenerative diseases and cancer. Aberrant VDAC1 activity connects with Alzheimer's disease due to its role in mitochondrial dysfunction affecting amyloid-beta peptide accumulation and neuronal cell death. In cancer VDAC overexpression associates with altered cellular metabolism and resistance to apoptosis positioning these proteins as potential therapeutic targets. Interactions with proteins such as hexokinase and Bcl-2 family members further emphasize their role in these pathological processes.
