Nonsense-mediated mRNA decay (NMD) eliminates transcripts carrying premature translation termination codons, but the role of NMD on yeast unspliced pre-mRNA degradation is controversial. Using tiling arrays, we show that many unspliced yeast pre-mRNAs accumulate in strains mutated for the NMD component Upf1p and the exonuclease Xrn1p. Intron identity and suboptimal splicing signals resulting in weak splicing were found to be important determinants in NMD targeting. In the absence of functional N ...[more]
