Abstract There are many quality-control mechanisms that ensure high fidelity of gene expression. One of these is the nonsense-mediated decay (NMD) pathway, which destroys aberrant mRNAs that contain premature termination codons generated as a result of biosynthetic errors or random and programmed gene mutations. Two complexes that initially bind to RNA in the nucleus have been suggested to be involved in NMD in the cytoplasm. Here we propose an alternative model that involves nuclear scanning, on the basis of recent evidence for nuclear translation.
