Voltage-dependent anion-selective channel protein 1

Gene

VDAC1

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

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.By similarity

Post-translational modificationi

Phosphorylation at Ser-193 by NEK1 promotes the open conformational state preventing excessive mitochondrial membrane permeability and subsequent apoptotic cell death after injury. Phosphorylation by the AKT-GSK3B axis stabilizes the protein probably by preventing ubiquitin-mediated proteasomal degradation.By similarity
Ubiquitinated by PARK2 during mitophagy, leading to its degradation and enhancement of mitophagy. Deubiquitinated by USP30.By similarity
