Abstract

A large share of the non-coding transcriptome in yeast is controlled by the Nrd1-Nab3-Sen1 (NNS) complex, which promotes transcription termination of non-coding RNA (ncRNA) genes, and by the nuclear exosome, which limits the steady-state levels of the transcripts produced. How unconstrained ncRNA levels affect RNA metabolism and gene expression are long-standing and important questions. Here, we show that degradation of ncRNAs by the exosome is required for freeing Nrd1 and Nab3 from the released transcript after termination. In exosome mutants, these factors are sequestered by ncRNAs and cannot be efficiently recycled to sites of transcription, inducing termination defects at NNS targets. ncRNA-dependent, genome-wide termination defects can be recapitulated by the expression of a degradation-resistant, circular RNA containing a natural NNS target in exosome-proficient cells. Our results have important implications for the mechanism of termination, the general impact of ncRNAs abundance, and the importance of nuclear ncRNA degradation.

  • Many transcripts differentially expressed in all five datasets were noncoding RNAs, which are well established targets for the RNA exosome and can include PROMPTs, antisense transcripts, and long noncoding RNAs.

    “Many of the transcripts that were differentially expressed in all five datasets were noncoding RNAs, which are well established to be targets for the RNA exosome and can include PROMPTs, antisense (AS) transcripts, and long noncoding RNAs (lncRNAs) as shown in Fig. 2B61–67.”

    The Introduction (p. 1) identifies noncoding RNAs, including cryptic unstable transcripts, as targets of exosome-mediated degradation and describes antisense noncoding transcription. It does not establish PROMPTs or long noncoding RNAs as examples of those targets. The five-dataset observation is the citing paper’s own result, not a finding attributed to this source.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
