A role for voltage-dependent anion channel Vdac1 in polyglutamine-mediated neuronal cell death. [PDF]

open access: yesPLoS ONE, 2007
Expansion of trinucleotide repeats in coding and non-coding regions of genes is associated with sixteen neurodegenerative disorders. However, the molecular effects that lead to neurodegeneration have remained elusive.

Porin 1 Modulates Autophagy in Yeast

open access: yesCells, 2021
Autophagy is a cellular recycling program which efficiently reduces the cellular burden of ageing. Autophagy is characterised by nucleation of isolation membranes, which grow in size and further expand to form autophagosomes, engulfing cellular material ...

Single-channel measurements of an N-acetylneuraminic acid-inducible outer membrane channel in Escherichia coli [PDF]

open access: yes, 2012
NanC is an Escherichia coli outer membrane protein involved in sialic acid (Neu5Ac, i.e., N-acetylneuraminic acid) uptake. Expression of the NanC gene is induced and controlled by Neu5Ac. The transport mechanism of Neu5Ac is not known.

Characterization of constitutive and acid-induced outwardly rectifying chloride currents in immortalized mouse distal tubular cells [PDF]

open access: yes, 2017
Thiazides block Na+ reabsorption while enhancing Ca2 + reabsorption in the kidney. As previously demonstrated in immortalized mouse DCT (MDCT) cells, chlorothiazide application induced a robust plasma membrane hyperpolarization, which increased Ca2 ...

β-Barrel Mobility Underlies Closure of the Voltage-Dependent Anion Channel [PDF]

open access: yesStructure, 2012
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.

Concentration dependent ion selectivity in VDAC: a molecular dynamics simulation study. [PDF]

open access: yesPLoS ONE, 2011
The voltage-dependent anion channel (VDAC) forms the major pore in the outer mitochondrial membrane. Its high conducting open state features a moderate anion selectivity.

Protocol: optimised electrophyiological analysis of intact guard cells from arabidopsis [PDF]

open access: yes, 2012
Genetic resources available for Arabidopsis thaliana make this species particularly attractive as a model for molecular genetic studies of guard cell homeostasis, transport and signalling, but this facility is not matched by accessible tools for ...

Dynamic change of electrostatic field in TMEM16F permeation pathway shifts its ion selectivity. [PDF]

open access: yes, 2019
TMEM16F is activated by elevated intracellular Ca2+, and functions as a small-conductance ion channel and as a phospholipid scramblase. In contrast to its paralogs, the TMEM16A/B calcium-activated chloride channels, mouse TMEM16F has been reported as a ...

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 ...

TSPO interacts with VDAC1 and triggers a ROS-mediated inhibition of mitochondrial quality control [PDF]

open access: yes, 2014
The 18-kDa TSPO (translocator protein) localizes on the outer mitochondrial membrane (OMM) and participates in cholesterol transport. Here, we report that TSPO inhibits mitochondrial autophagy downstream of the PINK1-PARK2 pathway, preventing essential ...
