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 …

High-resolution mapping of CCR4-NOT recruitment elements reveals transcriptome-wide drivers of mRNA decay.
Cell reports · 2026 · 45(5): 117348
The CCR4-NOT complex is a central regulator of gene expression, orchestrating mRNA turnover through interactions with RNA-binding proteins (RBPs) and the microRNA (miRNA)-induced silencing complex. However, identifying which RBP- and miRNA-associated RNA elements recruit CCR4-NOT remains challenging, due in part …

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 …

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 …

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 …

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 …

AKT constitutes a signal-promoted alternative exon-junction complex that regulates nonsense-mediated mRNA decay.
Molecular cell · 2022 · 82(15): 2779-2796.e10
Despite a long appreciation for the role of nonsense-mediated mRNA decay (NMD) in destroying faulty, disease-causing mRNAs and maintaining normal, physiologic mRNA abundance, additional effectors that regulate NMD activity in mammalian cells continue to be identified. Here, we describe a …

Context-dependent functional compensation between Ythdf m<sup>6</sup>A reader proteins.
Genes & development · 2020 · 34(19-20): 1373-1391
The N6-methyladenosine (m<sup>6</sup>A) modification is the most prevalent post-transcriptional mRNA modification, regulating mRNA decay and splicing. It plays a major role during normal development, differentiation, and disease progression. The modification is regulated by a set of writer, eraser, and reader …

The mRNA Decay Factor CAR-1/LSM14 Regulates Axon Regeneration via Mitochondrial Calcium Dynamics.
Current biology : CB · 2020 · 30(5): 865-876.e7
mRNA decay factors regulate mRNA turnover by recruiting non-translating mRNAs and targeting them for translational repression and mRNA degradation. How mRNA decay pathways regulate cellular function in vivo with specificity is poorly understood. Here, we show that C. elegans mRNA …

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 …

Biallelic mutations in the 3' exonuclease TOE1 cause pontocerebellar hypoplasia and uncover a role in snRNA processing.
Nature genetics · 2017 · 49(3): 457-464
Deadenylases are best known for degrading the poly(A) tail during mRNA decay. The deadenylase family has expanded throughout evolution and, in mammals, consists of 12 Mg<sup>2+</sup>-dependent 3'-end RNases with substrate specificity that is mostly unknown. Pontocerebellar hypoplasia type 7 (PCH7) …

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 …

The EJC factor eIF4AIII modulates synaptic strength and neuronal protein expression.
Cell · 2007 · 130(1): 179-91
Proper neuronal function and several forms of synaptic plasticity are highly dependent on precise control of mRNA translation, particularly in dendrites. We find that eIF4AIII, a core exon junction complex (EJC) component loaded onto mRNAs by pre-mRNA splicing, is associated …
