KIF5A binds RNA to orchestrate synaptic mRNA localization and stress granules in ALS.
bioRxiv : the preprint server for biology · 2025
Neuronal health depends on the precise transport and local translation of mRNAs to maintain synaptic function across highly polarized cellular architecture. While kinesin motor proteins are known to mediate mRNA transport, the specificity and direct involvement of individual kinesins as …

RNA triggers chronic stress during neuronal aging.
bioRxiv : the preprint server for biology · 2025
Neurodegenerative diseases are linked with dysregulation of the integrated stress response (ISR), which coordinates cellular homeostasis during and after stress events. Cellular stress can arise from several sources, but there is significant disagreement about which stress might contribute to aging …

Neuronal aging causes mislocalization of splicing proteins and unchecked cellular stress.
Nature neuroscience · 2025 · 28(6): 1174-1184
Aging is one of the most prominent risk factors for neurodegeneration, yet the molecular mechanisms underlying the deterioration of old neurons are mostly unknown. To efficiently study neurodegeneration in the context of aging, we transdifferentiated primary human fibroblasts from aged …

Large-scale map of RNA-binding protein interactomes across the mRNA life cycle.
Molecular cell · 2024 · 84(19): 3790-3809.e8
mRNAs interact with RNA-binding proteins (RBPs) throughout their processing and maturation. While efforts have assigned RBPs to RNA substrates, less exploration has leveraged protein-protein interactions (PPIs) to study proteins in mRNA life-cycle stages. We generated an RNA-aware, RBP-centric PPI map …

Large-scale map of RNA binding protein interactomes across the mRNA life-cycle.
bioRxiv : the preprint server for biology · 2023
Messenger RNAs (mRNAs) interact with RNA-binding proteins (RBPs) in diverse ribonucleoprotein complexes (RNPs) during distinct life-cycle stages for their processing and maturation. While substantial attention has focused on understanding RNA regulation by assigning proteins, particularly RBPs, to specific RNA substrates, …

APEX Proximity Labeling of Stress Granule Proteins.
Methods in molecular biology (Clifton, N.J.) · 2022 · 2428: 381-399
Ascorbate peroxidase (APEX)-catalyzed proximity labeling has been recently established as a robust approach to uncover localized protein environments and transient protein-protein interactions occurring across mammalian cells. This molecular tool enables improved identification of individual proteins localized to and involved in …

Aging RNA granule dynamics in neurodegeneration.
Frontiers in molecular biosciences · 2022 · 9: 991641
Disordered RNA-binding proteins and repetitive RNA sequences are the main genetic causes of several neurodegenerative diseases, including amyotrophic lateral sclerosis and Huntington's disease. Importantly, these components also seed the formation of cytoplasmic liquid-like granules, like stress granules and P bodies. …

Gain-of-function cardiomyopathic mutations in RBM20 rewire splicing regulation and re-distribute ribonucleoprotein granules within processing bodies.
Nature communications · 2021 · 12(1): 6324
Mutations in the cardiac splicing factor RBM20 lead to malignant dilated cardiomyopathy (DCM). To understand the mechanism of RBM20-associated DCM, we engineered isogenic iPSCs with DCM-associated missense mutations in RBM20 as well as RBM20 knockout (KO) iPSCs. iPSC-derived engineered heart …

Persistent mRNA localization defects and cell death in ALS neurons caused by transient cellular stress.
Cell reports · 2021 · 36(10): 109685
Persistent cytoplasmic aggregates containing RNA binding proteins (RBPs) are central to the pathogenesis of late-onset neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS). These aggregates share components, molecular mechanisms, and cellular protein quality control pathways with stress-induced RNA granules (SGs). …

Huntington's disease mice and human brain tissue exhibit increased G3BP1 granules and TDP43 mislocalization.
The Journal of clinical investigation · 2021 · 131(12)
Chronic cellular stress associated with neurodegenerative disease can result in the persistence of stress granule (SG) structures, membraneless organelles that form in response to cellular stress. In Huntington's disease (HD), chronic expression of mutant huntingtin generates various forms of cellular …

Pooled CRISPR screens with imaging on microraft arrays reveals stress granule-regulatory factors.
Nature methods · 2020 · 17(6): 636-642
Genetic screens using pooled CRISPR-based approaches are scalable and inexpensive, but restricted to standard readouts, including survival, proliferation and sortable markers. However, many biologically relevant cell states involve cellular and subcellular changes that are only accessible by microscopic visualization, and …

Small-Molecule Modulation of TDP-43 Recruitment to Stress Granules Prevents Persistent TDP-43 Accumulation in ALS/FTD.
Neuron · 2019 · 103(5): 802-819.e11
Stress granules (SGs) form during cellular stress and are implicated in neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD). To yield insights into the role of SGs in pathophysiology, we performed a high-content screen to identify small …

Active Protein Neddylation or Ubiquitylation Is Dispensable for Stress Granule Dynamics.
Cell reports · 2019 · 27(5): 1356-1363.e3
Stress granule (SG) formation is frequently accompanied by ubiquitin proteasome system (UPS) impairment and ubiquitylated protein accumulation. SGs, ubiquitin, and UPS components co-localize, but the relationship between the ubiquitin pathway and SGs has not been systematically characterized. We utilize pharmacological …
