Strategies for programmable manipulation of alternative splicing.
Current opinion in genetics & development · 2024 · 89: 102272
Alternative splicing (AS) plays a pivotal role in protein diversity and mRNA maturation. Programmable control of targeted AS events is of longstanding interest in RNA biology, promising correction of dysregulated splicing in disease and discovery of AS events. This review …

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 …

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 …

A super-enhancer-regulated RNA-binding protein cascade drives pancreatic cancer.
Nature communications · 2023 · 14(1): 5195
Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy in need of new therapeutic options. Using unbiased analyses of super-enhancers (SEs) as sentinels of core genes involved in cell-specific function, here we uncover a druggable SE-mediated RNA-binding protein (RBP) cascade that …

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, …

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 …

Context-Dependent and Disease-Specific Diversity in Protein Interactions within Stress Granules.
Cell · 2018 · 172(3): 590-604.e13
Stress granules (SGs) are transient ribonucleoprotein (RNP) aggregates that form during cellular stress and are increasingly implicated in human neurodegeneration. To study the proteome and compositional diversity of SGs in different cell types and in the context of neurodegeneration-linked mutations, …

Robust transcriptome-wide discovery of RNA-binding protein binding sites with enhanced CLIP (eCLIP).
Nature methods · 2016 · 13(6): 508-14
As RNA-binding proteins (RBPs) play essential roles in cellular physiology by interacting with target RNA molecules, binding site identification by UV crosslinking and immunoprecipitation (CLIP) of ribonucleoprotein complexes is critical to understanding RBP function. However, current CLIP protocols are technically …

The Clothes Make the mRNA: Past and Present Trends in mRNP Fashion.
Annual review of biochemistry · 2015 · 84: 325-54
Throughout their lifetimes, messenger RNAs (mRNAs) associate with proteins to form ribonucleoproteins (mRNPs). Since the discovery of the first mRNP component more than 40 years ago, what is known as the mRNA interactome now comprises >1,000 proteins. These proteins bind …

A regulator of Dscam mutually exclusive splicing fidelity.
Nature structural & molecular biology · 2007 · 14(12): 1134-40
The Down syndrome cell adhesion molecule (Dscam) gene has essential roles in neural wiring and pathogen recognition in Drosophila melanogaster. Dscam encodes 38,016 distinct isoforms via extensive alternative splicing. The 95 alternative exons in Dscam are organized into clusters that …
