Quinidine partially blocks mitochondrial voltage-dependent anion channel (VDAC)
European Biophysics Journal, 2020Quinidine is an antiarrhythmic drug commonly used for the treatment of cardiac ailments. It affects oxidative phosphorylation, calcium uptake, and ion channels of mitochondria. We have investigated the interaction of Quinidine and mitochondrial voltage-dependent anion channel (VDAC).

Expression and localization of voltage-dependent anion channels (VDAC) in human spermatozoa
Biochemical and Biophysical Research Communications, 2009Voltage-dependent anion channels (VDAC), also known as mitochondrial porins, are a group of proteins first identified in the mitochondrial outer membrane that are able to form hydrophilic pore structures. VDAC allow the passage of the metabolites across the mitochondrial outer membrane, and are involved in metabolite transport and signal transduction ...

Transmembrane arrangement of mitochondrial porin or voltage-dependent anion channel (VDAC)
Journal of Bioenergetics and Biomembranes, 1992Porin or voltage-dependent anion-selective channel (VDAC) is the main protein responsible for the high permeability of the outer mitochondrial membrane. The mitochondrial porin is mainly composed of sided beta-strands, in analogy with bacterial porin, whose structure has been resolved at 1.8 A resolution.

Voltage-Dependent Anion Channel (VDAC) in Health and Disease
2023Abstract The voltage-dependent anion channel (VDAC) is recognized as the key metabolite pathway of water-soluble metabolites, small ions, and polypeptides across the outer mitochondrial membrane. The significance of this relatively simple β-barrel channel arises from its crucial position at the interface between the mitochondria and ...

Modulation of the voltage-dependent anion channel (VDAC) by glutamate.
Journal of bioenergetics and biomembranes, 2009The voltage-dependent anion channel (VDAC), also known as mitochondrial porin, is a large channel permeable to anions, cations, ATP, and other metabolites. VDAC was purified from sheep brain synaptosomes or rat liver mitochondria using a reactive red-agarose column, in addition to the hydroxyapatitate column.

Voltage-dependent anion channel (VDAC) as mitochondrial governator—Thinking outside the box
Biochimica Et Biophysica Acta - Molecular Basis of Disease, 2006 Despite a detailed understanding of their metabolism, mitochondria often behave anomalously. In particular, global suppression of mitochondrial metabolism and metabolite exchange occurs in apoptosis, ischemia and anoxia, cytopathic hypoxia of sepsis and multiple organ failure, alcoholic liver disease, aerobic glycolysis in cancer cells (Warburg effect)

Localisation and function of voltage-dependent anion channels (VDAC) in bovine spermatozoa
Pflügers Archiv - European Journal of Physiology, 2007Sperm motility, regulation of cell volume, sperm capacitation, acrosome reaction and tight binding of spermatozoa to the zona pellucida are crucial events in the process of fertilisation. Voltage-dependent anion channels (VDAC) are highly conserved pore-forming proteins implicated in apoptosis, metabolite transport between mitochondria and cytosol ...

Purification of VDAC (Voltage-dependent anion-selective channel) from rat liver mitochondria
Journal of Membrane Biology, 1983The outer membrane of rat liver mitochondria contains a channel-forming protein known as VDAC (voltage-dependent anion-selective channel). This protein has been functionally purified by a combination of ion exchange chromatography, gel filtration and affinity chromatography on a Concanavalin A-containing column.

Structural Analysis of Murine Voltage Dependent Anion Channel (VDAC) 1
The FASEB Journal, 2006VDAC is a mammalian integral protein expressed in the outer mitochondrial membrane. It has a bi‐functional role in mitochondrial biology: under physiological conditions, it transports nucleotides and small molecules across the outer membrane and
