Human Gene VDAC2 (ENST00000543351.5)
  Description: Homo sapiens voltage dependent anion channel 2 (VDAC2), transcript variant 2, mRNA. (from RefSeq NM_003375)
RefSeq Summary (NM_001184823): This gene encodes a member of the voltage-dependent anion channel pore-forming family of proteins that are considered the main pathway for metabolite diffusion across the mitochondrial outer membrane. The encoded protein is also thought to be involved in the mitochondrial apoptotic pathway via regulation of BCL2-antagonist/killer 1 protein activity. Pseudogenes have been identified on chromosomes 1, 2, 12 and 21, and alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010].

DESCRIPTION: RecName: Full=Voltage-dependent anion-selective channel protein 2; Short=VDAC-2; Short=hVDAC2; AltName: Full=Outer mitochondrial membrane protein porin 2;
FUNCTION: Forms a channel through the mitochondrial outer membrane that allows diffusion of small hydrophilic molecules. The channel 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.
SUBUNIT: Interacts with hexokinases (By similarity).
INTERACTION: Q96A26:FAM162A; NbExp=2; IntAct=EBI-354022, EBI-6123466;
SUBCELLULAR LOCATION: Mitochondrion outer membrane.
TISSUE SPECIFICITY: Expressed in all tissues examined.
DOMAIN: Consists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands (By similarity).
SIMILARITY: Belongs to the eukaryotic mitochondrial porin family.
SEQUENCE CAUTION: Sequence=CAH73106.1; Type=Erroneous gene model prediction; Sequence=CAI40910.1; Type=Erroneous gene model prediction;

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on P45880
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
