Nucleotide Interactions of the Human Voltage-dependent Anion Channel [PDF]
The voltage-dependent anion channel (VDAC) mediates and gates the flux of metabolites and ions across the outer mitochondrial membrane and is a key player in cellular metabolism and apoptosis. Here we characterized the binding of nucleotides to human VDAC1 (hVDAC1) on a single-residue level using NMR spectroscopy and site-directed mutagenesis.

VDAC: Voltage Dependant Anion Channel
VDAC (Voltage Dependent Anion Channel) is a channel protein located on the outer mitochondrial membrane. It regulates mitochondria functions and cell respiration through the exchange of molecules between the cytoplasm and the organelle, such as ADP, ATP, anions, cations, and other small, hydrophilic molecules.

Subcellular Localization of Human Voltage-dependent Anion Channel Isoforms [PDF]
The voltage-dependent anion channel of the outer mitochondrial membrane, VDAC (also known as mitochondrial porin), is a small abundant protein which forms a voltage-gated pore when incorporated into planar lipid bilayers. This protein forms the primary pathway for movement of major metabolites through the outer membrane.

Neuroactive Steroids: Receptor Interactions and Responses
Neuroactive steroids (NASs) are naturally occurring steroids, which are synthesized centrally as de novo from cholesterol and are classified as pregnane, androstane, and sulfated neurosteroids (NSs).

β-Barrel Mobility Underlies Closure of the Voltage-Dependent Anion Channel [PDF]
The voltage-dependent anion channel (VDAC) is the major protein in the outer mitochondrial membrane, where it mediates transport of ATP and ADP. Changes in its permeability, induced by voltage or apoptosis-related proteins, have been implicated in apoptotic pathways.

LRRC8/VRAC anion channels enhance β-cell glucose sensing and insulin secretion
Insulin secretion by β-cells is stimulated by glucose and is dependent on the induction of β-cell membrane depolarization, mainly driven by the closure of KATP channels, which in turn promotes voltage-gated Ca2+ channel opening.

Physiology and pathophysiology of ClC-K/barttin channels
ClC-K channels form a subgroup of anion channels within the ClC family of anion transport proteins. They are expressed predominantly in the kidney and in the inner ear, and are necessary for NaCl resorption in the loop of Henle and for K+ secretion by ...

Voltage-Dependent Anion Selective Channel Isoforms in Yeast: Expression, Structure, and Functions
Mitochondrial porins, also known as voltage-dependent anion selective channels (VDACs), are pore-forming molecules of the outer mitochondrial membranes, involved in the regulation of metabolic flux between cytosol and mitochondria.

Arabidopsis voltage-dependent anion channel 1 (AtVDAC1) is required for female development and maintenance of mitochondrial functions related to energy-transaction. [PDF]
The voltage-dependent anion channels (VDACs), prominently localized in the outer mitochondrial membrane, play important roles in the metabolite exchange, energy metabolism and mitochondria-mediated apoptosis process in mammalian cells.
