SG formation relies on eIF4GI-G3BP interaction which is targeted by picornavirus stress antagonists [PDF]

Cell Discovery, 2019
AbstractTypical stress granules (tSGs) are stalled translation pre-initiation complex aggregations in the cytoplasm, and their formation is a common consequence of translation initiation inhibition under stress. We previously found that 2A protease of picornaviruses blocks tSG formation and induces atypical SG formation, but the molecular mechanism by ...

Phospho-Rasputin Stabilization by Sec16 Is Required for Stress Granule Formation upon Amino Acid Starvation

Cell Reports, 2017
Most cellular stresses induce protein translation inhibition and stress granule formation. Here, using Drosophila S2 cells, we investigate the role of G3BP/Rasputin in this process.

On subcellular distribution of the zinc finger 469 protein (ZNF469) and observed discrepancy in the localization of endogenous and overexpressed ZNF469

FEBS Open Bio, Volume 15, Issue 7, Page 1054-1067, July 2025.
ZNF469 regulates the expression of genes encoding extracellular matrix proteins. Endogenous ZNF469 is predominantly cytoplasmic, while in transfected cells, it forms aggregates reminiscent of biomolecular condensates, located mainly in the nucleus. These condensates exhibit overlapping staining with proteasomes and are also associated with the mitotic ...

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron

Advanced Science, Volume 12, Issue 26, July 10, 2025.
This study aimed to unravel the role of FUS in the loading of functional circRNAs into neuronal sEVs under hypoxic conditions, which involves their aggregations in SGs and specific interaction between the FUS Zf_RanBP domain to regulate circRNA sorting in sEVs.

Heregulin induces expression, Atpase activity and nuclear localization of G3bp, a Ras signaling component, in human breast tumors

, 2002
We have found using differential display of mRNA that the growth factor heregulin β1 (HRG), a combinatorial ligand for human epidermal growth factor receptors (HERs), induced expression of G3BP, the Ras GTPase-activating protein SH3 domain-binding ...

Mitochondria and Endoplasmic Reticulum Contact Site as a Regulator of Proteostatic Stress Responses in Neurodegenerative Diseases

BioEssays, Volume 47, Issue 7, July 2025.
Recent findings indicate that mitochondria‐associated membranes (MAMs), where the endoplasmic reticulum directly contacts the mitochondria, are a novel microdomain essential for cellular homeostasis, including proteostasis. We summarize the disruption of protein homeostasis and MAM alteration in neurodegenerative diseases, then discuss challenges and ...

Investigation of the Role of G3BP in Stress Granule Formation in Senescence [PDF]

, 2022
Senescent cells accumulate with age and are defined as the cells that irreversibly lose their ability to proliferate. They are characterized by an enlarged flat cell phenotype, enlarged nucleus with persistent DNA damage foci, and an increase in ...

Phase Separation Regulates Metabolism, Mitochondria, and Diseases

MedComm, Volume 6, Issue 7, July 2025.
Mitochondrion‐related liquid–liquid phase separation. (1) Phase separation mediates the self‐assembly of mitochondrial nucleoids (mt‐nucleoids). (2) Phase segregation mediates the formation of mitochondrial RNA granules (MRGs). (3) Phase separation mediates the formation of mitochondrial degradosomes.

Cataloguing and Selection of mRNAs Localized to Dendrites in Neurons and Regulated by RNA-Binding Proteins in RNA Granules

Biomolecules, 2020
Spatiotemporal translational regulation plays a key role in determining cell fate and function. Specifically, in neurons, local translation in dendrites is essential for synaptic plasticity and long-term memory formation.

The Role of Chikungunya nsP3 in Regulating G3BP Activity, Stress Granule Formation and Drug Efficacy

, 2018
Ras-GTPase activating protein SH3 domain binding proteins (G3BP) are a small family of RNA-binding proteins that have been implicated in regulating gene expression when a cell undergoes transformation or in response to external stimuli.
