Sequestration of TRAF2 into stress granules interrupts tumor necrosis factor signaling under stress conditions.
The cellular stress response (SR) is a phylogenetically conserved protection mechanism that involves inhibition of protein synthesis through recruitment of translation factors such as eIF4G into insoluble stress granules (SGs) and blockade of proinflammatory responses by interruption of the signaling pathway from tumor necrosis factor alpha (TNF-alpha) to nuclear factor-kappaB (NF-kappaB) activ...
متن کاملSequestration of Highly Expressed mRNAs in Cytoplasmic Granules, P-Bodies, and Stress Granules Enhances Cell Viability
Transcriptome analyses indicate that a core 10%-15% of the yeast genome is modulated by a variety of different stresses. However, not all the induced genes undergo translation, and null mutants of many induced genes do not show elevated sensitivity to the particular stress. Elucidation of the RNA lifecycle reveals accumulation of non-translating mRNAs in cytoplasmic granules, P-bodies, and stre...
متن کاملStress granules are dispensable for mRNA stabilization during cellular stress
During cellular stress, protein synthesis is severely reduced and bulk mRNA is recruited to stress granules (SGs). Previously, we showed that the SG-recruited IGF2 mRNA-binding protein 1 (IGF2BP1) interferes with target mRNA degradation during cellular stress. Whether this requires the formation of SGs remained elusive. Here, we demonstrate that the sustained inhibition of visible SGs requires ...
متن کاملStress granules
Cell growth and proliferation are fundamental processes in living organisms and are dynamically controlled by environmental cues. TOR complex 1 (TORC1) is a central protein kinase involved in the regulation of cell growth in response to a wide variety of cellular states and is the target of the immunosuppressant and anticancer drug rapamycin. In the budding yeast Saccharomyces cerevisiae, TORC1...
متن کاملStress granules
What are stress granules? Stress granules are non-membranous cytoplasmic foci ranging in size from 0.1 to 2.0 μm, composed of non-translating messenger ribonucleoproteins (mRNPs) that rapidly aggregate in cells exposed to adverse environmental conditions. Their assembly is triggered by a variety of environmental stresses including heat shock, oxidative stress, hyperosmolarity, viral infection, ...
