Is there a classical nonsense-mediated decay pathway in trypanosomes? [PDF]
PLoS ONE, 2011 In many eukaryotes, messenger RNAs with premature termination codons are destroyed by a process called "nonsense-mediated decay", which requires the RNA helicase Upf1 and also, usually, an interacting factor, Upf2.

SMG5-SMG7 authorize nonsense-mediated mRNA decay by enabling SMG6 endonucleolytic activity
Nature Communications, 2021 Degradation of nonsense mediated mRNA decay (NMD) substrates is carried out by two seemingly independent pathways, SMG6-mediated endonucleolytic cleavage and/or SMG5-SMG7-induced accelerated deadenylation.

Insights into the assembly and architecture of a Staufen-mediated mRNA decay (SMD)-competent mRNP
Nature Communications, 2019 The Staufen proteins recognize secondary structures in 3’-untranslated regions in mRNA transcripts and induce degradation of these mRNAs with the help of the RNA helicase UPF1.

Nonsense-mediated mRNA decay in the ADAMTS13 gene caused by a 29-nucleotide deletion
Haematologica, 2008 Background In mammalian cells a regulatory mechanism, known as nonsense-mediated mRNA decay, degrades mRNA harboring premature termination codons. This mechanism is intron-dependent and functions as a quality control mechanism to eliminate abnormal ...

When a ribosome encounters a premature termination codon [PDF]
BMB Reports, 2013 In mammalian cells, aberrant transcripts harboring a prematuretermination codon (PTC) can be generated by abnormal orinefficient biogenesis of mRNAs or by somatic mutation.Truncated polypeptides synthesized from these aberranttranscripts could be toxic ...

MicroRNA-mediated repression of nonsense mRNAs
eLife, 2014 Numerous studies have established important roles for microRNAs (miRNAs) in regulating gene expression. Here, we report that miRNAs also serve as a surveillance system to repress the expression of nonsense mRNAs that may produce harmful truncated ...

Nonsense-mediated mRNA decay factor UPF1 promotes aggresome formation
Nature Communications, 2020 Nonsense-mediated mRNA decay (NMD) is a translation-coupled process that eliminates mRNAs containing premature translation-termination codons. Here the authors identify a role for the NMD factor UPF1 in protein quality control, whereby truncated ...

A system for coordinated analysis of translational readthrough and nonsense-mediated mRNA decay. [PDF]
PLoS ONE, 2017 The nonsense-mediated mRNA decay (NMD) pathway degrades mRNAs containing premature termination codons, limiting the expression of potentially deleterious truncated proteins.

Nonsense-mediated mRNA decay uses complementary mechanisms to suppress mRNA and protein accumulation
Life Science Alliance, 2022 A reporter system for quantitative measurements of NMD-sensitive mRNA and protein levels in mammalian cells shows that NMD suppresses protein levels to a greater degree than RNA levels. Nonsense-mediated mRNA decay (NMD) is an essential, highly conserved

Nonsense-mediated mRNA decay among coagulation factor genes [PDF]
Iranian Journal of Basic Medical Sciences, 2016 Objective(s): Haemostasis prevents blood loss following vascular injury. It depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors.
