Stress 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, ...
متن کاملYeast processing bodies and stress granules: self-assembly ribonucleoprotein particles
Processing bodies (PBs) and stress granules (SGs) are two highly conserved cytoplasmic ribonucleoprotein foci that contain translationally repressed mRNAs together with proteins from the mRNA metabolism. Interestingly, they also share some common features with other granules, including the prokaryotic inclusion bodies. Although the function of PBs and SGs remains elusive, major advances have be...
متن کاملProteomics of rice grain under high temperature stress
Recent proteomic analyses revealed dynamic changes of metabolisms during rice grain development. Interestingly, proteins involved in glycolysis, citric acid cycle, lipid metabolism, and proteolysis were accumulated at higher levels in mature grain than those of developing stages. High temperature (HT) stress in rice ripening period causes damaged (chalky) grains which have loosely packed round ...
