Establishment of an in vitro transport assay that reveals mechanistic differences in cytosolic events controlling cholera toxin and T-cell receptor α retro-translocation. [PDF]

PLoS ONE, 2013
Following retrograde trafficking to the endoplasmic reticulum (ER), cholera toxin A1 (CTA1) subunit hijacks ER-associated degradation (ERAD) machinery and retro-translocates into the cytosol to induce toxicity.

A guide to reactive oxygen species in tumour hypoxia: measurement and therapeutic implications

Molecular Oncology, EarlyView.
Hypoxia reshapes tumour redox landscapes by altering compartmental ROS production (mitochondria, NOX, ER, peroxisomes). Accurate interpretation requires oxygen‐contextualised measurement (live biosensors, chemical probes, EPR, LC–MS) and awareness of artefacts (reoxygenation, probe specificity).

In vitro conversion of squalene from squalene-phospholipid liposomes into sterols by rat liver microsomes and cytosol

Journal of Lipid Research, 1980
When rat liver cytosol, possessing sterol carrier protein (SCP) activity was incubated with [3H]-squalene-phospholipid liposomes, cofactors, and rat liver microsomes, squalene from the liposomes was converted into sterols.

Regulatory assembly of the vacuolar proton pump VOV1-ATPase in yeast cells by FLIM-FRET

, 2010
We investigate the reversible disassembly of VOV1-ATPase in life yeast cells by time resolved confocal FRET imaging. VOV1-ATPase in the vacuolar membrane pumps protons from the cytosol into the vacuole. VOV1-ATPase is a rotary biological nanomotor driven

Short‐term actions of epigalocatechin‐3‐gallate in the liver: a mechanistic insight into hypoglycemic and potential toxic effects

FEBS Open Bio, EarlyView.
Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

SGTA regulates the cytosolic quality control of hydrophobic substrates [PDF]

, 2014
Hydrophobic amino acids are normally shielded from the cytosol and their exposure is often used as an indicator of protein misfolding to enable the chaperone-mediated recognition and quality control of aberrant polypeptides.

Homologous expression and purification of human HAX‐1 for structural studies

FEBS Open Bio, EarlyView.
This research protocol provides detailed instructions for cloning, expressing, and purifying large quantities of the intrinsically disordered human HAX‐1 protein, N‐terminally fused to a cleavable superfolder GFP, from mammalian cells. HAX‐1 is predicted to undergo posttranslational modifications and to interact with membranes, various cellular ...

Identification, purification, and immunochemical characterization of a tocopherol-binding protein in rat liver cytosol.

Journal of Lipid Research, 1992
Tocopherol binding activity accompanying a rat liver cytosolic protein with molecular weight of 30-36 kDa has been demonstrated previously, although the isolation of the protein has not been reported. We now report the purification of an alpha-tocopherol-

Sensitisation waves in a bidomain fire-diffuse-fire model of intracellular Ca²⁺ dynamics [PDF]

, 2009
We present a bidomain threshold model of intracellular calcium (Ca²⁺) dynamics in which, as suggested by recent experiments, the cytosolic threshold for Ca²⁺ liberation is modulated by the Ca²⁺ concentration in the releasing compartment.

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.
