A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.

Attaching a molecule of adenosine mono-phosphate (AMP) to the BiP protein at threonine 518 regulates its chaperone activity in the endoplasmic reticulum.

Proteins of the reticulon and REEP families, homologous to the products of human Hereditary Spastic Paraplegia disease genes, contribute to shaping and continuity of the axonal endoplasmic reticulum network in Drosophila.

The coordination of protein targeting to the endoplasmic reticulum and the unfolded protein response through the stress sensor IRE1 ensures quality control of the secreted and transmembrane proteomes.

Immunoisolation combined with quantitative proteomics identifies 79 proteins enriched in the tubular endoplasmic reticulum and provides useful tool for analyzing this organelle's functions.

Selective docking of HAC1 mRNA on Ire1 clusters at a site separate from the Ire1 RNase domain is key for endoplasmic reticulum stress signaling.

The extent of (proteotoxic) endoplasmic reticulum stress, and the ensuing unfolded protein response activation, are commensurate with the extent of the chaperone BiP being sequestered by its client proteins.

Full length RTN3 homodimerization mediates ER tubules fragmentation and their subsequent delivery to lysosome.

Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.

Adapting a cytosolic enzyme that breaks down glutathione to function in the lumen of the endoplasmic reticulum challenges the long-held view that reduced glutathione fuels disulfide rearrangements during protein folding.
