(Submitter supplied) We performed a fluorescent reporter based screen to identify factors determining transcriptional directionality from bidirectional promoters that give rise to a coding and a non-coding transcript. Promoters like these are most frequent in many organisms and non-coding transcription from this origin represents a large fraction of total long non-coding transcripts. We applied NET-seq to compare nascent transcription in yeast wild-type and mutations in the three members of the CAF-I complex. more...

(Submitter supplied) Eukaryotic cells utilize several mechanisms to ensure that expression of aberrant non-coding RNAs is limited. Gene looping, chromatin modification or remodeling, and RNA surveillance contribute to ensure the fidelity of transcription and limit non-coding transcripts. Here we identify that in Saccharomyces cerevisiae, the transcription factor Rap1 is critical for limiting the expression of aberrant RNAs, particularly near the highly expressed ribosomal protein genes, and characterize them in the context of other non-coding RNAs regulated by chromatin and transcription related factors.

(Submitter supplied) Many active eukaryotic gene promoters exhibit divergent noncoding transcription, but the mechanisms restricting expression of these transcripts are not well understood. Here we demonstrate how a sequence-specific transcription factor represses divergent noncoding transcription at highly expressed genes in yeast. We find that depletion of the transcription factor Rap1 induces noncoding transcription in a large fraction of Rap1 regulated gene promoters. more...

(Submitter supplied) It has previously been shown that Isw2 represses cryptic antisense transcripts from the 3’-end of three genes. However, whether Isw2 generally functions to repress cryptic RNA transcription is currently unknown. We thus sought to determine the loci at which Isw2 is required to repress cryptic non-coding RNA (ncRNA) expression and to map their transcription start sites relative to nucleosome positions on a global scale.

(Submitter supplied) ISWI-family chromatin remodelers organize nucleosome arrays, while SWI/SNF-family remodelers (RSC) disorganize and eject nucleosomes, implying an antagonism that is largely unexplored in vivo. Here, we describe two independent genetic screens for rsc suppressors that yielded mutations in the promoter-focused ISW1a complex, or mutations in the ‘basic patch’ of histone H4 (an epitope that regulates ISWI activity), strongly supporting RSC-ISW1a antagonism in vivo. more...
