Stress granule homeostasis is modulated by TRIM21-mediated ubiquitination of G3BP1 and autophagy-dependent elimination of stress granules

Autophagy, 2023
Eukaryotic stress granules (SGs) are highly dynamic assemblies of untranslated mRNAs and proteins that form through liquid-liquid phase separation (LLPS) under cellular stress.

Stress granules: regulators or by‐products?

The FEBS Journal, 2021
Cells have to deal with conditions that can cause damage to biomolecules and eventually cell death. To protect against these adverse conditions and promote recovery, cells undergo dramatic changes upon exposure to stress. This involves activation of signaling pathways, cell cycle arrest, translational reprogramming, and reorganization of the cytoplasm.

Yeast stress granules at a glance

Yeast, 2021
AbstractThe formation of stress granules (SGs), membrane‐less organelles that are composed of mainly messenger ribonucleoprotein assemblies, is the result of a conserved evolutionary strategy to cellular stress. During their formation, which is triggered by robust environmental stress, SGs sequester translationally inactive mRNA molecules, which are ...

A Narrative Review on Stress Granules and Ultraviolet Stress Granules

Photobiomodulation, Photomedicine, and Laser Surgery
Background: Stress granules (SGs) are membraneless structures formed through liquid–liquid phase separation in response to cellular stress. These dynamic assemblies play a pivotal role in cellular adaptation and recovery from external stressors by modulating protein synthesis and preserving mRNA integrity ...

Regulation of stress granule formation in human oligodendrocytes

Nature Communications
Oligodendrocyte (OL) injury and subsequent loss is a pathologic hallmark of multiple sclerosis (MS). Stress granules (SGs) are membrane-less organelles containing mRNAs stalled in translation and considered as participants of the cellular response to ...

FAM98A is localized to stress granules and associates with multiple stress granule-localized proteins

Molecular and Cellular Biochemistry, 2018
Stress granules are evolutionally conserved ribonucleoprotein structures that are formed in response to various stress stimuli. Recent studies have demonstrated that proteins with low complexity (LC) regions play a critical role for the formation of stress granules.
