Localized regulation of cell junction mRNAs is required for epithelial cell integrity.
RNA (New York, N.Y.) · 2026 · 32(5): 635-653
Epithelial cells exhibit a highly polarized organization along their apico-basal axis, a feature that is critical to their function and is frequently perturbed in cancer. One less explored process modulating epithelial cell polarity is the subcellular localization of mRNA molecules. …

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 …

Enhancing RNA base editing on mammalian transcripts with small nuclear RNAs.
Nature chemical biology · 2025
Endogenous uridine-rich small nuclear RNAs (U snRNAs) form RNA-protein complexes to process eukaryotic pre-mRNA into mRNA. Previous studies have demonstrated programmable U snRNA guide-targeted exon inclusion and exclusion. Here we investigated whether snRNAs can also enhance RNA base editing over …

Localized molecular chaperone synthesis maintains neuronal dendrite proteostasis.
Nature communications · 2024 · 15(1): 10796
Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted protein folding. However, this is challenging in neuronal projections because of their polarized morphology and constant synaptic proteome remodeling. Using high-resolution fluorescence microscopy, we discover that hippocampal and spinal …

Localized synthesis of molecular chaperones sustains neuronal proteostasis.
bioRxiv : the preprint server for biology · 2024
Neurons are challenged to maintain proteostasis in neuronal projections, particularly with the physiological stress at synapses to support intercellular communication underlying important functions such as memory and movement control. Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted …

Small nuclear RNAs enhance protein-free RNA-programmable base conversion on mammalian coding transcripts.
bioRxiv : the preprint server for biology · 2024
Endogenous U small nuclear RNAs (U snRNAs) form RNA-protein complexes responsible for eukaryotic processing of pre-mRNA into mature mRNA. Previous studies have demonstrated the utility of guide-programmable U snRNAs in targeted exon inclusion and exclusion. We investigated whether snRNAs can …

ePRINT: exonuclease assisted mapping of protein-RNA interactions.
Genome biology · 2024 · 25(1): 140
RNA-binding proteins (RBPs) regulate key aspects of RNA processing including alternative splicing, mRNA degradation and localization by physically binding RNA molecules. Current methods to map these interactions, such as CLIP, rely on purifying single proteins at a time. Our new …

Transcriptome regulation by PARP13 in basal and antiviral states in human cells.
iScience · 2024 · 27(4): 109251
The RNA-binding protein PARP13 is a primary factor in the innate antiviral response, which suppresses translation and drives decay of bound viral and host RNA. PARP13 interacts with many proteins encoded by interferon-stimulated genes (ISG) to activate antiviral pathways including …

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). …

Tethered Function Assays as Tools to Elucidate the Molecular Roles of RNA-Binding Proteins.
Advances in experimental medicine and biology · 2016 · 907: 61-88
Dynamic regulation of RNA molecules is critical to the survival and development of cells. Messenger RNAs are transcribed in the nucleus as intron-containing pre-mRNAs and bound by RNA-binding proteins, which control their fate by regulating RNA stability, splicing, polyadenylation, translation, …

Programmable RNA Tracking in Live Cells with CRISPR/Cas9.
Cell · 2016 · 165(2): 488-96
RNA-programmed genome editing using CRISPR/Cas9 from Streptococcus pyogenes has enabled rapid and accessible alteration of specific genomic loci in many organisms. A flexible means to target RNA would allow alteration and imaging of endogenous RNA transcripts analogous to CRISPR/Cas-based genomic …

Genome-wide approaches to dissect the roles of RNA binding proteins in translational control: implications for neurological diseases.
Frontiers in neuroscience · 2012 · 6: 144
Translational control of messenger RNAs (mRNAs) is a key aspect of neurobiology, defects of which can lead to neurological diseases. In response to stimuli, local translation of mRNAs is activated at synapses to facilitate long-lasting forms of synaptic plasticity, the …
