Cellular Stress Induces Nucleocytoplasmic Transport Deficits Independent of Stress Granules
Stress granules are non-membrane bound granules temporarily forming in the cytoplasm in response to stress. Proteins of the nucleocytoplasmic transport machinery were found in these stress granules and it was suggested that stress granules contribute to ...

EGFP-FMRP Granules Are Proto-Granules That Can Be Shunted to Stress Granules During a Stress Response [PDF]
AbstractOverexpressed EGFP-FMRP has been used as a substitute for endogenous fragile X mental retardation protein (FMRP) in protein-protein interaction studies, and in studies concerning the composition, the formation and the localization of neuronal granules.

Aspergillus oryzae AoSO is a novel component of stress granules upon heat stress in filamentous fungi. [PDF]
Stress granules are a type of cytoplasmic messenger ribonucleoprotein (mRNP) granule formed in response to the inhibition of translation initiation, which typically occurs when cells are exposed to stress.

Stress‐induced mRNP granules: Form and function of processing bodies and stress granules [PDF]
In response to stress, cells must quickly reprogram gene expression to adapt and survive. This is achieved in part by altering levels of mRNAs and their translation into proteins. Recently, the formation of two stress‐induced messenger ribonucleoprotein (mRNP) assemblies named stress granules and processing bodies has been postulated to directly impact

Getting stress out of stressed‐out stress granules [PDF]
Amyotrophic lateral sclerosis (ALS) pathology is linked to the aberrant aggregation of specific proteins, including TDP‐43, FUS, and SOD1, but it is not clear why these aggregation events cause ALS. In this issue of The EMBO Journal , Mateju et al (2017) report a direct link between misfolded proteins accumulating in stress granules and the phase ...

Sequestration of highly expressed mRNAs in cytoplasmic granules, P-bodies, and stress granules enhances cell viability. [PDF]
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 ...

Stress Granules and Virus Replication [PDF]
Viruses are dependent on the cellular translation machinery for protein synthesis. Part of the innate immune response to infection is activation of the stress kinase PKR which phosphorylates the alpha subunit of the initiation factor eIF2. This results in inhibition of translation and is intended to block virus replication.

Ribonucleoprotein Granules: Between Stress and Transposable Elements
Transposable elements (TEs) are DNA sequences that can transpose and replicate within the genome, leading to genetic changes that affect various aspects of host biology.

Rim4-seeded stress granules connect temperature sensing to meiotic regulation
Meiosis is more vulnerable to heat than mitosis in many species including humans. In Saccharomyces cerevisiae, we discovered that stress granule formation halts meiosis at high temperatures. Meiotic stress granules appear at lower temperatures (33–42 °C)

Composition and Dynamics of Stress Granules [PDF]
Stress granules are non-membranous assemblies of RNA and protein that form during conditions in which translation initiation is limited. Stress granules are of interest due to their potential role in the regulation of gene expression and their relation ...
