Messenger RNA (mRNA) degradation is a process that plays an important role in the regulation of gene expression and can be linked to translation. Study of the nonsense-mediated mRNA decay pathway has greatly aided our understanding of the link between these processes. Evidence indicates that this pathway regulates the abundance of both aberrant and wild-type transcripts. Factors involved in this pathway have been identified and recent results indicate that they might also be involved in modulating translation. Here, we discuss the mechanism of nonsense-mediated mRNA decay in the yeast Saccharomyces cerevisiae and the potential role that this pathway can have on the regulation of gene expression.
