Aberrant host mRNA partitioning in Ebola virus condensates driven by RNA folding perpetuates species-dependent interferon response.
bioRxiv : the preprint server for biology · 2026
RNA viruses form membraneless condensates in host cells to drive replication, but whether these compartments also regulate host RNAs remains unclear. Using MERFISH-based subcellular transcriptomics, we quantified cellular mRNA recruitment into Ebola virus condensates under basal and IFN-stimulated states. We …

Structural and mechanistic analysis of covalent ligands targeting the RNA-binding protein NONO.
Cell chemical biology · 2026 · 33(2): 256-267.e11
RNA-binding proteins (RBPs) play important roles in mRNA transcription, processing, and translation. Chemical tools are lacking for RBPs, which has hindered efforts to perturb and understand RBP function in cells. We previously described a chloroacetamide compound (R)-SKBG-1 that covalently binds …

Human CCR4 deadenylase homolog Angel1 is a non-stop mRNA decay factor.
RNA (New York, N.Y.) · 2025 · 31(8): 1195-1205
Translation elongation stalls trigger mRNA decay and degradation of the nascent polypeptide via translation-dependent quality control pathways. One such pathway, non-stop mRNA decay (NSD), targets aberrant mRNAs that lack stop codons, for example, due to premature polyadenylation. Here we identify …

Structural and mechanistic analysis of covalent ligands targeting the RNA-binding protein NONO.
bioRxiv : the preprint server for biology · 2025
RNA-binding proteins (RBPs) play important roles in mRNA transcription, processing, and translation. Chemical tools are lacking for RBPs, which has hindered efforts to perturb and understand RBP function in cells. We recently reported a chloroacetamide compound ( <i>R</i> )-SKBG-1 that …

circHIPK3 nucleates IGF2BP2 and functions as a competing endogenous RNA.
bioRxiv : the preprint server for biology · 2024
Circular RNAs (circRNAs) represent a class of widespread endogenous RNAs that regulate gene expression and thereby influence cell biological decisions with implications for the pathogenesis of several diseases. Here, we disclose a novel gene-regulatory role of circHIPK3 by combining analyses …

A phage nucleus-associated RNA-binding protein is required for jumbo phage infection.
bioRxiv : the preprint server for biology · 2023
Large-genome bacteriophages (jumbo phages) of the <i>Chimalliviridae</i> family assemble a nucleus-like compartment bounded by a protein shell that protects the replicating phage genome from host-encoded restriction enzymes and CRISPR/Cas nucleases. While the nuclear shell provides broad protection against host nucleases, …

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 …

Remodeling oncogenic transcriptomes by small molecules targeting NONO.
Nature chemical biology · 2023 · 19(7): 825-836
Much of the human proteome is involved in mRNA homeostasis, but most RNA-binding proteins lack chemical probes. Here we identify electrophilic small molecules that rapidly and stereoselectively decrease the expression of transcripts encoding the androgen receptor and its splice variants …

In Vivo Screening Unveils Pervasive RNA-Binding Protein Dependencies in Leukemic Stem Cells and Identifies ELAVL1 as a Therapeutic Target.
Blood cancer discovery · 2023 · 4(3): 180-207
Acute myeloid leukemia (AML) is fueled by leukemic stem cells (LSC) whose determinants are challenging to discern from hematopoietic stem cells (HSC) or uncover by approaches focused on general cell properties. We have identified a set of RNA-binding proteins (RBP) …

Splicing factor SRSF1 deficiency in the liver triggers NASH-like pathology and cell death.
Nature communications · 2023 · 14(1): 551
Regulation of RNA processing contributes profoundly to tissue development and physiology. Here, we report that serine-arginine-rich splicing factor 1 (SRSF1) is essential for hepatocyte function and survival. Although SRSF1 is mainly known for its many roles in mRNA metabolism, it …

Inhibition of YTHDF2 triggers proteotoxic cell death in MYC-driven breast cancer.
Molecular cell · 2021 · 81(15): 3048-3064.e9
RNA-binding proteins (RBPs) are critical regulators of post-transcriptional gene expression, and aberrant RBP-RNA interactions can promote cancer progression. Here, we interrogate the function of RBPs in cancer using pooled CRISPR-Cas9 screening and identify 57 RBP candidates with distinct roles in …

Large-scale tethered function assays identify factors that regulate mRNA stability and translation.
Nature structural & molecular biology · 2020 · 27(10): 989-1000
The molecular functions of the majority of RNA-binding proteins (RBPs) remain unclear, highlighting a major bottleneck to a full understanding of gene expression regulation. Here, we develop a plasmid resource of 690 human RBPs that we subject to luciferase-based 3'-untranslated-region …

Short poly(A) tails are a conserved feature of highly expressed genes.
Nature structural & molecular biology · 2017 · 24(12): 1057-1063
Poly(A) tails are important elements in mRNA translation and stability, although recent genome-wide studies have concluded that poly(A) tail length is generally not associated with translational efficiency in nonembryonic cells. To investigate whether poly(A) tail size might be coupled to …

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, …

Enhanced CLIP Uncovers IMP Protein-RNA Targets in Human Pluripotent Stem Cells Important for Cell Adhesion and Survival.
Cell reports · 2016 · 15(3): 666-679
Human pluripotent stem cells (hPSCs) require precise control of post-transcriptional RNA networks to maintain proliferation and survival. Using enhanced UV crosslinking and immunoprecipitation (eCLIP), we identify RNA targets of the IMP/IGF2BP family of RNA-binding proteins in hPSCs. At the broad …

Comprehensive identification of miRNA target sites in live animals.
Methods in molecular biology (Clifton, N.J.) · 2011 · 732: 169-85
MicroRNAs (miRNAs) are small RNA molecules that posttranscriptionally regulate the expression of protein-coding genes. The mature miRNAs are loaded into Argonaute-containing protein complexes (miRISC, miRNA Induced S ilencing Complex), and guide these complexes to the 3' UTR of targeted mRNA …
