Nonsense-mediated mRNA decay: terminating erroneous gene expression.

Current Opinion in Cell Biology, 2004
Nonsense-mediated mRNA decay is a surveillance pathway that reduces errors in gene expression by eliminating aberrant mRNAs that encode incomplete polypeptides. Recent experiments suggest a working model whereby premature and normal translation termination events are distinct as a consequence of the spatial relationship between the termination codon ...

Circular RNAs trigger nonsense-mediated mRNA decay.

open access: yesMolecular Cell
Circular RNAs (circRNAs) are covalently closed single-stranded RNAs produced predominantly through a back-splicing process. They play regulatory roles in various biological and physiological processes; however, the molecular mechanisms by which circRNAs ...

Nonsense-mediated mRNA decay (NMD) mechanisms

Nature Structural & Molecular Biology, 2009
Nonsense-mediated mRNA decay (NMD) is a translation-coupled mechanism that eliminates mRNAs containing premature translation-termination codons (PTCs). In mammalian cells, NMD is also linked to pre-mRNA splicing, as in many instances strong mRNA reduction occurs only when the PTC is located upstream of an intron.
