Integrative CRISPR Screening and RNA Analyses Discover an Essential Role for PUF60 Interactions with 3' Splice Sites in Cancer Progression.
Cancer research · 2025
RNA-binding proteins (RBPs) are important regulators of post-transcriptional gene expression. Understanding which and how RBPs promote cancer progression is crucial for cancers that lack effective targeted therapies, such as triple negative breast cancer (TNBC). Here, we employed both in vitro …

Integrative CRISPR Screens and RNA-Omics Discover an Essential Role for PUF60-3' Splice Site Interactions in Cancer Progression.
bioRxiv : the preprint server for biology · 2025
RNA-binding proteins (RBPs) are important regulators of post-transcriptional gene expression. Understanding which and how RBPs promote cancer progression is crucial for cancers that lack effective targeted therapies such as triple negative breast cancer (TNBC). Here, we employ both <i>in vitro</i> …

Phenylpyrazoles as Inhibitors of the m<sup>6</sup>A RNA-Binding Protein YTHDF2.
JACS Au · 2025 · 5(2): 618-630
The <i>N</i>6-methyladenosine (m<sup>6</sup>A) modification, which is the most common RNA modification in eukaryotes, is regulated by the "writer" methyltransferases, the "reader" m<sup>6</sup>A binding proteins, and the "eraser" demethylases. m<sup>6</sup>A plays a multifunctional role in physiological and pathological processes, regulating all …

Integrated multi-omics analysis of zinc-finger proteins uncovers roles in RNA regulation.
Molecular cell · 2024 · 84(19): 3826-3842.e8
RNA interactome studies have revealed that hundreds of zinc-finger proteins (ZFPs) are candidate RNA-binding proteins (RBPs), yet their RNA substrates and functional significance remain largely uncharacterized. Here, we present a systematic multi-omics analysis of the DNA- and RNA-binding targets and …

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 …

Epistatic interactions between NMD and TRP53 control progenitor cell maintenance and brain size.
Neuron · 2024 · 112(13): 2157-2176.e12
Mutations in human nonsense-mediated mRNA decay (NMD) factors are enriched in neurodevelopmental disorders. We show that deletion of key NMD factor Upf2 in mouse embryonic neural progenitor cells causes perinatal microcephaly but deletion in immature neurons does not, indicating NMD's …

A phage nucleus-associated RNA-binding protein is required for jumbo phage infection.
Nucleic acids research · 2024 · 52(8): 4440-4455
Large-genome bacteriophages (jumbo phages) of the proposed family Chimalliviridae assemble a nucleus-like compartment bounded by a protein shell that protects the replicating phage genome from host-encoded restriction enzymes and DNA-targeting CRISPR-Cas nucleases. While the nuclear shell provides broad protection against …

Examination of the Cell Cycle Dependence of Cytosine and Adenine Base Editors.
Frontiers in genome editing · 2022 · 4: 923718
Base editors (BEs) are genome editing agents that install point mutations with high efficiency and specificity. Due to their reliance on uracil and inosine DNA damage intermediates (rather than double-strand DNA breaks, or DSBs), it has been hypothesized that BEs …

RNA binding protein DDX5 directs tuft cell specification and function to regulate microbial repertoire and disease susceptibility in the intestine.
Gut · 2022 · 71(9): 1790-1802
Tuft cells residing in the intestinal epithelium have diverse functions. In the small intestine, they provide protection against inflammation, combat against helminth and protist infections, and serve as entry portals for enteroviruses. In the colon, they had been implicated in …

Illuminating RNA biology through imaging.
Nature cell biology · 2022 · 24(6): 815-824
RNA processing plays a central role in accurately transmitting genetic information into functional RNA and protein regulators. To fully appreciate the RNA life-cycle, tools to observe RNA with high spatial and temporal resolution are critical. Here we review recent advances …

Pseudouridine synthases modify human pre-mRNA co-transcriptionally and affect pre-mRNA processing.
Molecular cell · 2022 · 82(3): 645-659.e9
Pseudouridine is a modified nucleotide that is prevalent in human mRNAs and is dynamically regulated. Here, we investigate when in their life cycle mRNAs become pseudouridylated to illuminate the potential regulatory functions of endogenous mRNA pseudouridylation. Using single-nucleotide resolution pseudouridine …

A role for alternative splicing in circadian control of exocytosis and glucose homeostasis.
Genes & development · 2020 · 34(15-16): 1089-1105
The circadian clock is encoded by a negative transcriptional feedback loop that coordinates physiology and behavior through molecular programs that remain incompletely understood. Here, we reveal rhythmic genome-wide alternative splicing (AS) of pre-mRNAs encoding regulators of peptidergic secretion within pancreatic …

A Small RNA-Catalytic Argonaute Pathway Tunes Germline Transcript Levels to Ensure Embryonic Divisions.
Cell · 2016 · 165(2): 396-409
Multiple division cycles without growth are a characteristic feature of early embryogenesis. The female germline loads proteins and RNAs into oocytes to support these divisions, which lack many quality control mechanisms operating in somatic cells undergoing growth. Here, we describe …

Target Discrimination in Nonsense-Mediated mRNA Decay Requires Upf1 ATPase Activity.
Molecular cell · 2015 · 59(3): 413-25
RNA quality-control pathways get rid of faulty RNAs and therefore must be able to discriminate these RNAs from those that are normal. Here we present evidence that the adenosine triphosphatase (ATPase) cycle of the SF1 helicase Upf1 is required for …

RNA sequence analysis defines Dicer's role in mouse embryonic stem cells.
Proceedings of the National Academy of Sciences of the United States of America · 2007 · 104(46): 18097-102
Short RNA expression was analyzed from Dicer-positive and Dicer-knockout mouse embryonic [corrected] stem (ES) cells, using high-throughput pyrosequencing. A correlation of miRNA quantification with sequencing frequency estimates that there are 110,000 miRNAs per ES cell, the majority of which can …
