Function
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. -
Tissue specificity
Heart, liver and skeletal muscle. -
Sequence similarities
Belongs to the eukaryotic mitochondrial porin family. -
Domain
Consists 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 localization
Mitochondrion outer membrane. Cell membrane. - Information by UniProt

ab14734 was shown to react with VDAC1 / Porin in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab255444 (knockout cell lysate ab263839) was used. Wild-type and VDAC1 / Porin knockout samples were subjected to SDS-PAGE. ab14734 and Anti-GAPDH antibody [EPR16891] - Loading Control (ab181602) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Observed band size: 37 kDa why is the actual band size different from the predicted?
Extra bands in the mouse sample (lane 4) are due to the reaction of the secondary antibody with residual mouse blood in the heart tissue, as it is very difficult to entirely remove the blood from these small organs. -

Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 for 3 minutes and blocked with 0.2% serum for 60 minutes at 22°C. Samples were incubated with primary antibody (1/200 in 0.5% BSA and 0.02% Triton X100 in PBS) for 16 hours at 4°C. An FITC-conjugated goat anti-mouse IgG polyclonal was used as the secondary antibody at a dilution of 1/200.

The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab14734, 1 µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2 µg/1x106 cells) used under the same conditions.
Acquisition of >5,000 events was performed.
This antibody gave a positive signal in HepG2 cells fixed with 80% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
