Stress granule dynamics
WebStress granules (SGs) are conserved biomolecular condensates that originate in response to many stress conditions. These membraneless organelles contain nontranslating mRNAs … WebAug 1, 2016 · Alterations in the dynamics of stress granules have been reported in several other forms of ALS unrelated to SOD1. To our surprise, the mutant G93A SOD1 transgenic mice exhibited pathological cytoplasmic inclusions that co-localized with G3BP1-positive granules in spinal cord motor neurons.

WebMar 1, 2010 · 1.. IntroductionStress granules (SGs) are formed in eukaryotic cells in response to acute stress conditions, such as oxidative stress, UV irradiation, and heat shock [1], [2], [3].SGs are dense particles ranging from about 1 µm to several microns in size.SGs accumulate components of the 48S pre-initiatory complexes (mRNAs, small ribosomal … WebStress granules formation is connected to several diseases, including neurodegeneration. The formation of SGs is considered a pro-survival strategy in neurons to ease out the intermittent stresses. However, persistent stress and mutation in RNA binding proteins could increase SGs in the neuron that could be toxic leading to pathology.
WebMar 29, 2024 · Phosphorylation of eIF2α is directly related to the dynamics of stress granules (SGs), which are membraneless organelles composed of RNA-binding proteins and mRNA. SGs play a critical role in mRNA metabolism and translational control.
