Target
- 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. May participate in the formation of the permeability transition pore complex (PTPC) responsible for the release of mitochondrial products that triggers apoptosis.
- Tissue specificityHeart, liver and skeletal muscle.
- Sequence similaritiesBelongs to the eukaryotic mitochondrial porin family.
- DomainConsists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands. The helical N-terminus folds back into the pore opening and plays a role in voltage-gated channel activity.
- Cellular localizationMitochondrion outer membrane. Cell membrane.

Immunocytochemistry/ Immunofluorescence - VDAC1 / Porin antibody - Mitochondrial Loading Control (ab15895)ICC/IF image of ab15895 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab15895, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 phalloidin was used to label F-actin (red).
