FAQ
Stress granules are non-membrane bound RNA-protein (RNP) assemblies that form when translation initiation is limited and contain a biphasic structure with stable core structures surrounded by a less concentrated shell. The order of assembly and disassembly of these two structures remains unknown.
Stress granules are assemblies of untranslating mRNPs that form from mRNAs stalled in translation initiation. Stress granules form through interactions between mRNA binding proteins that link together populations of mRNPs.
In brief, the approach used is that stress granules are first isolated from stressed cultures and enriched using centrifugation. Stress granules are further purified using immunoprecipitation with antibodies against known stress granule components.
Stress granules form through interactions between mRNA binding proteins that link together populations of mRNPs. Interactions promoting stress granule formation include conventional protein-protein interactions, as well as interactions involving intrinsically disordered regions of proteins.
Stress granules (SGs) are non-enveloped structures formed primarily via protein and RNA aggregation under various stress conditions, including hypoxia and viral infection, as well as oxidative, osmotic, and heat-shock stress.
Taken together, stress granule disassembly may occur through multiple steps wherein RNA is titrated out of stress granule into translation leading to structural instability and subsequent disassembly of a larger stress granule complex into smaller core structures that are then disassembled or cleared by autophagy.
