Cytoplasmic mrnp granules at a glance
WebSmall cytoplasmic mRNP granules are implicated in mRNA transport, translational control, and decay. Using super-resolution microscopy and fluores-cence correlation … Webcytoplasmic mRNP granules, we will discuss the protein complexes required for the assembly of mRNPs into PBs and SGs, the conditions under which assembly occurs and the potential outcomes of assembling mRNPs into large macromolecular complexes. This discussion is relevant also to other cytoplasmic mRNP granules, for example those …

WebSep 1, 2024 · Stress-induced cytoplasmic RNA–protein granules were first described in mammalian cells (Kedersha et al. 1999), whereas PBs in mammalian cells were first described as cytoplasmic foci enriched in 5′-3′ exoribonuclease 1 (mXRN1p) ( Bashkirov et al., 1997 ). Orthologs of both may be found throughout eukaryota ( Guzikowski et al., … WebJan 16, 2024 · Processing bodies (PBs) are cytoplasmic mRNP granules that assemble via liquid-liquid phase separation and are implicated in the decay or storage of mRNAs. How PB assembly is regulated in cells remains unclear. Previously, we identified the ATPase activity of the DEAD-box protein Dhh1 as a key regul …
WebStress granules (SGs) are transient, cytoplasmic mRNP granules that form following translational inhibition and contribute to the regulation of gene expression during cellular stress [ 47 ]. SGs contain numerous RBPs including TDP43, which interacts with both RNAs and proteins within these structures [ 48 ]. WebJul 16, 2008 · Abstract In mammals, repression of translation during stress is associated with the assembly of stress granules in the cytoplasm, which contain a fraction of arrested mRNA and have been proposed to play a role in their storage.
