Cell-free electrophysiology of human VDACs incorporated into nanodiscs: An improved method

open access: yesBiophysical Reports, 2021
Voltage-dependent anion-selective channel (VDAC) is one of the main proteins of the outer mitochondrial membrane of all eukaryotes, where it forms aqueous, voltage-sensitive, and ion-selective channels.

MicroED structure of lipid-embedded mammalian mitochondrial voltage-dependent anion channel [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance Microcrystal electron diffraction (MicroED) is an electron cryo-microscopy (cryoEM) method for determining structures using submicron crystals. Until now, determining structures of membrane proteins by MicroED required that the protein crystals be in a solution amenable to standard cryoEM blotting and vitrification ...

SWELL1 is a glucose sensor regulating β-cell excitability and systemic glycaemia

open access: yesNature Communications, 2018
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. Here Kang et al.

A C-Terminally Truncated Variant of Neurospora crassa VDAC Assembles Into a Partially Functional Form in the Mitochondrial Outer Membrane and Forms Multimers in vitro

open access: yesFrontiers in Physiology, 2021
The voltage-dependent anion-selective channel (VDAC) is a porin in the mitochondrial outer membrane (MOM). Unlike bacterial porins, several mitochondrial β-barrels comprise an odd number of β-strands, as is the case for the 19-β-stranded VDAC. Previously,

Voltage-Dependent Anion-Selective Channels and Other Mitochondrial Membrane Proteins Form Diverse Complexes in Beetroots Subjected to Flood-Induced Programmed Cell Death

open access: yesFrontiers in Plant Science, 2021
In plants, programmed cell death (PCD) is involved in both the development and the response to biotic and abiotic aggressions. In early stages of PCD, mitochondrial membranes are made permeable by the formation of permeability transition pores, whose ...

Isolation of a novel human voltage-dependent anion channel gene [PDF]

open access: yesEuropean Journal of Human Genetics, 1998
The voltage-dependent anion channel of the mitochondrial outer membrane (VDAC) is a small, abundant pore-forming protein found in the outer membranes of all eukaryotic mitochondria. The VDAC protein is believed to control the movement of adenine nucleotides through the outer membrane and to be the mitochondrial binding site for hexokinase and glycerol ...

Recombinant yeast VDAC2: a comparison of electrophysiological features with the native form

open access: yesFEBS Open Bio, 2019
Voltage‐dependent anion channel isoform 2 of the yeast Saccharomyces cerevisiae (yVDAC2) was believed for many years to be devoid of channel activity. Recently, we isolated yVDAC2 and showed that it exhibits channel‐forming activity in the planar lipid ...

Two-electrode Voltage-clamp Recordings in Xenopus laevis Oocytes:Reconstitution of Abscisic Acid Activation of SLAC1 Anion Channel via PYL9 ABA Receptor

open access: yesBio-Protocol, 2017
Two-Electrode Voltage-Clamp (TEVC) recording in Xenopus laevis oocytes provides a powerful method to investigate the functions and regulation of ion channel proteins.

Novel hybrid action of GABA mediates inhibitory feedback in the mammalian retina.

open access: yesPLoS Biology, 2019
The stream of visual information sent from photoreceptors to second-order bipolar cells is intercepted by laterally interacting horizontal cells that generate feedback to optimize and improve the efficiency of signal transmission.

Intracellular ion channels and cancer

open access: yesFrontiers in Physiology, 2013
Several types of channels play a role in the maintenance of ion homeostasis in subcellular organelles including endoplasmatic reticulum, nucleus, lysosome, endosome and mitochondria.
