High-throughput gene expression analysis has revealed a plethora of previously undetected transcripts in eukaryotic cells. In this study we investigate >1100 unannotated transcripts in yeast predicted to lack protein-coding capacity. We show that a majority of these RNAs are enriched on polyribosomes akin to mRNAs. Ribosome profiling demonstrates that many bind translocating ribosomes within predicted open-reading frames 10–96 codons in size. We validate expression of peptides encoded within a subset of these RNAs and provide evidence for conservation among yeast species. Consistent with their translation, many of these transcripts are targeted for degradation by the translation-dependent, nonsense-mediated RNA decay (NMD) pathway. We identify lncRNAs also sensitive to NMD, indicating translation of non-coding transcripts also occurs in mammals. These data demonstrate transcripts considered to lack coding potential are bona fide protein-coding, and expand the proteome of yeast and possibly other eukaryotes.
