Upf1 Phosphorylation Triggers Translational Repression during Nonsense-Mediated mRNA Decay [PDF]

, 2008
SummaryIn mammalian cells, nonsense-mediated mRNA decay (NMD) generally requires that translation terminates sufficiently upstream of a post-splicing exon junction complex (EJC) during a pioneer round of translation. The subsequent binding of Upf1 to the

Nonsense-Mediated mRNA Decay Factor Functions in Human Health and Disease

Biomedicines, 2023
Nonsense-mediated mRNA decay (NMD) is a cellular surveillance mechanism that degrades mRNAs with a premature stop codon, avoiding the synthesis of C-terminally truncated proteins. In addition to faulty mRNAs, NMD recognises ~10% of endogenous transcripts

A rhesus macaque model of α‐dystroglycanopathy caused by a POMT1 splice altering variant

Animal Models and Experimental Medicine, EarlyView.
Rhesus macaques homozygous for a naturally occurring spice altering variant in the POMT1 gene develop lissencephaly, microphthalmia, and muscular contracture. The presentation models severe presentation of the human Walker‐Warburg syndrome. Abstract Background Biallelic mutations in genes associated with α‐dystroglycan glycosylation manifest in a ...

The Substrates of Nonsense-Mediated mRNA Decay in Caenorhabditis elegans

G3: Genes, Genomes, Genetics, 2018
Nonsense-mediated mRNA decay (NMD) is a conserved pathway that strongly influences eukaryotic gene expression. Inactivating or inhibiting NMD affects the abundance of a substantial fraction of the transcriptome in numerous species.

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Nonsense‐mediated decay targets have multiple sequence‐related features that can inhibit translation

Molecular Systems Biology, 2010
Nonsense‐mediated mRNA decay (NMD) is a surveillance system that eliminates transcripts with premature termination codons. In this study, we show that mRNAs targeted by NMD are also suppressed at the translational level. The low translational efficiency (

Inhibition of post-termination ribosome recycling at premature termination codons in UPF1 ATPase mutants

eLife, 2020
Recognition and rapid degradation of mRNA harboring premature translation termination codons (PTCs) serves to protect cells from accumulating non-functional and potentially toxic truncated polypeptides. Targeting of PTC-containing transcripts is mediated

MiniSdd7‐Derived Cytosine Base Editor Promotes Efficient Multiplex Gene Knockout in Porcine Primary Fibroblasts

Animal Research and One Health, EarlyView.
The miniSdd7‐BE4max‐SpG system enables highly efficient multiplex C‐to‐T base editing of APN, CD163, and MSTN in porcine fibroblasts, providing a robust platform for future development of multiplex gene‐edited livestock. ABSTRACT Efficient multiplex genome editing is essential for improving complex traits in livestock that are governed by multiple ...

Characterization of nonsense mediated mRNA decay in Schizosaccharomyces pombe [PDF]

, 2010
Nonsense mediated mRNA decay (NMD) is a translation-coupled process that preferentially destroys mRNAs harboring premature translation termination codons (PTCs). In mammalian cells, NMD is linked to pre-mRNA splicing.

Nonsense-mediated mRNA decay (NMD) restricts replication of mammalian RNA viruses

, 2014
A genome-wide siRNA screen against host factors that affect the infection of Semliki Forest virus (SFV), a positive-strand (+)RNA virus, revealed that components of the nonsense-mediated mRNA decay (NMD) pathway restrict early, post-entry steps of the ...
