A dual-color TIRFM study reveals a new form of inflammatory regulation, in which a lipid kinase and ion channel reciprocally regulate each other to amplify the response to painful stimuli.
The soluble cargo protein albumin traverses the Golgi stack at much faster rates than procollagen aggregates, by diffusion via intercisternal continuities.
Plasticity arising from autocatalytic receptor activation coexists with robustness in ligand responsiveness only by differential endosomal sorting of spontaneous and ligand-activated EGFR as distinct molecular states.
Engineering cytokines to exhibit different receptor binding dwell times is a useful strategy to decouple their functional pleiotropy and reduce their toxicity in the clinic.
Studies of Lowe syndrome patient cells, which lack the inositol 5-phosphatase OCRL, suggest that a defect in endocytosis plays a role in the pathological manifestations of the disease.
A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.
Phosphorylation of a core trafficking component, the COPII coat subunit Sec24, regulates cross-talk between the secretory and autophagy machinery during starvation.
ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.
