When a ribosome encounters a premature termination codon [PDF]
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
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
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]
The nonsense-mediated mRNA decay (NMD) pathway degrades mRNAs containing premature termination codons, limiting the expression of potentially deleterious truncated proteins.

Interaction of yeast eIF4G with spliceosome components Implications in pre-mRNA processing events [PDF]
As evidenced from mammalian cells the eukaryotic translation initiation factor eIF4G has a putative role in nuclear RNA metabolism. Here we investigate whether this role is conserved in the yeast Saccharomyces cerevisiae.

Nonsense-mediated mRNA decay: novel mechanistic insights and biological impact [PDF]
Nonsense-mediated mRNA decay (NMD) was originally coined to define a quality control mechanism that targets mRNAs with truncated open reading frames due to the presence of a premature termination codon.

Nonsense-mediated mRNA decay uses complementary mechanisms to suppress mRNA and protein accumulation
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

On the role of ras and BRF1 in the regulation of ARE-dependent mRNA-turnover [PDF]
Stability of the mRNAs of cytokines, chemokines, growth-factors, protooncogenes and others are regulated via an AU-rich element (ARE) in their 3’ untranslated region (UTR).

Nonsense-mediated mRNA decay among coagulation factor genes [PDF]
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.

The involvement of DIS3L2 in nonsense-mediated mRNA decay and its functional networks in cancer
DIS3L2, member of the highly conserved RNase II family, is a 3’-5’ exoribonuclease that degrades different types of RNAs in an exosome-independent manner, including mRNAs and several types of non-coding RNAs.
