CC -!- FUNCTION: Forms a channel through the mitochondrial outer membrane and
CC also the plasma membrane. The channel at the outer mitochondrial
CC membrane allows diffusion of small hydrophilic molecules; in the plasma
CC membrane it is involved in cell volume regulation and apoptosis. It
CC adopts an open conformation at low or zero membrane potential and a
CC closed conformation at potentials above 30-40 mV. The open state has a
CC weak anion selectivity whereas the closed state is cation-selective.
CC Binds various signaling molecules, including the sphingolipid ceramide,
CC the phospholipid phosphatidylcholine, and the sterol cholesterol. In
CC depolarized mitochondria, acts downstream of PRKN and PINK1 to promote
CC mitophagy or prevent apoptosis; polyubiquitination by PRKN promotes
CC mitophagy, while monoubiquitination by PRKN decreases mitochondrial
CC calcium influx which ultimately inhibits apoptosis. May participate in
CC the formation of the permeability transition pore complex (PTPC)
CC responsible for the release of mitochondrial products that triggers
CC apoptosis. May mediate ATP export from cells.
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- ACTIVITY REGULATION: Inhibited by nitric oxide.
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- SUBUNIT: Homodimer and homotrimer; in response to cyclic AMP or
CC calcium. Interacts with hexokinases including HK1. The HK1-VDAC1
CC complex interacts with ATF2. Interacts with BCL2L1. Interacts with
CC BAK1. Interacts with RTL10/BOP (via BH3 domain). Interacts with
CC amyloid-beta and APP; induces VDAC1 dephosphorylation. Component of the
CC mitochondrial permeability transition pore complex (mPTPC), at least
CC composed of SPG7, VDAC1 and PPIF. Interacts with SPG7, NIPSNAP2 and
CC SLC25A30. Interacts with TMEM41B. Interacts with BCAP31.
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane
CC {ECO:0000250|UniProtKB:P21796}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P21796}. Cell membrane
CC {ECO:0000250|UniProtKB:P21796}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P21796}. Membrane raft
CC {ECO:0000250|UniProtKB:P21796}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- DOMAIN: Consists mainly of a membrane-spanning beta-barrel formed by 19
CC beta-strands. The helical N-terminus folds back into the pore opening
CC and plays a role in voltage-gated channel activity.
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- PTM: Phosphorylation at Ser-193 by NEK1 promotes the open
CC conformational state preventing excessive mitochondrial membrane
CC permeability and subsequent apoptotic cell death after injury.
CC Phosphorylation by the AKT-GSK3B axis stabilizes the protein probably
CC by preventing ubiquitin-mediated proteasomal degradation.
CC {ECO:0000250|UniProtKB:P21796}.
CC -!- PTM: Ubiquitinated. Undergoes monoubiquitination and polyubiquitination
CC by PRKN; monoubiquitination at Lys-274 inhibits apoptosis, whereas
CC polyubiquitination leads to its degradation and promotes mitophagy.
CC Deubiquitinated by USP30. {ECO:0000250|UniProtKB:P21796}.
CC -!- MISCELLANEOUS: Dicyclohexylcarbodiimide (DCCD) binding on Glu-73
CC inhibits hexokinase binding in vitro. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the eukaryotic mitochondrial porin family.
CC {ECO:0000305}.
