TranscriptomicsGlobal analysis of mRNA decay intermediates in Saccharomyces cerevisiae
The general pathways of eukaryotic mRNA decay occur via deadenylation followed by 3’ to 5’ degradation or decapping, although some endonuclease sites have been identified in metazoan mRNAs. To determine the role of endonucleases in mRNA degradation in Saccharomyces cerevisiae, we mapped 5’ monophosp...

TranscriptomicsNET-seq of S. cerevisiae cells after knocking-out genes encoding various mRNA decay factors
NET-seq was performed on yeast strains carrying deletions of mRNA decay factors (plus a control) in order to assess the effect of their deletion on RNA polymerase II occupancy at genetic loci. This is in pursuit of understanding the process of mRNA buffering which links mRNA synthesis and decay.

ProteomicsRNA-controlled nucleocytoplasmic shuttling of mRNA decay factors regulates mRNA synthesis and a novel mRNA decay pathway
mRNA level is controlled by factors that mediate both mRNA synthesis and decay, including the 5’ to 3’ exonuclease Xrn1 - a major mRNA synthesis and decay factor. Here we show that nucleocytoplasmic shuttling of several mRNA decay factors plays a key role in determining both mRNA synthesis and decay...

ProteomicsMolecular mechanisms of recruitment, function and regulation of the RNA helicase UPF1 in replication-dependent histone mRNA decay
Metazoan histone mRNAs are a unique class of mRNAs that lack the poly(A) tail present in all other eukaryotic transcripts. Instead, they end in a conserved stem-loop (SL) structure, necessitating a decay mechanism that is distinct from deadenylation-initiated degradation. Here, combining cryoEM with...

TranscriptomicsPervasive TTP binding but selective target mRNA destabilization in the macrophage transcriptome [RNA-Seq_2]
Precise control of mRNA decay is fundamental for robust yet not exaggerated inflammatory responses to pathogens. Parameters determining the specificity and extent of mRNA degradation within the entire inflammation-associated transcriptome remain incompletely understood. Using transcriptome-wide high...

TranscriptomicsWidespread Co-translational RNA Decay Reveals Ribosome Dynamics
It is generally assumed that mRNAs undergoing translation are protected from decay. Here, we show that mRNAs are, in fact, co-translationally degraded. This is a widespread and conserved process affecting most genes, where 5′–3′ transcript degradation follows the last translating ribosome, producing...

TranscriptomicsRNAi knock down of known nonsense-mediated mRNA decay (NMD) factors in Drosophila cells
All eukaryotes studied to date have the capacity to detect and degrade mRNAs harboring premature translation termination codons (PTCs) in a process called nonsense-mediated mRNA decay (NMD) (reviewed in Wagner E & Lykke-Andersen J, 2002). This surveillance system allows the cell to prevent the expre...

TranscriptomicsHuman Nonsense-Mediated RNA Decay Initiates Widely by Endonucleolysis and Targets snoRNA Host Genes
Eukaryotic RNAs with premature termination codons (PTCs) are eliminated by nonsense-mediated decay (NMD). While human nonsense RNA degradation can be initiated either by an endonucleolytic cleavage event near the PTC or through decapping, the individual contribution of these activities on endogenous...

TranscriptomicsQuality control of transcription start site selection by Nonsense-Mediated-mRNA Decay
Nonsense-mediated mRNA decay (NMD) is a translation-dependent RNA quality-control pathway targeting transcripts such as messenger RNAs harboring premature stop-codons or short upstream open reading frame (uORFs). Our transcription start sites (TSSs) analysis of Saccharomyces cerevisiae cells deficie...

mRNA decay in E. Coli degradosome mutants and their parental strains following transcriptional arrest with rifampicin. Abstract: RNase E, an essential endoribonuclease of Escherichia coli, interacts through its C-terminal region with multiple other proteins to form a complex termed the RNA degradoso...
