(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) 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) 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) Abf1 and Rap1 are General Regulatory Factors that contribute to transcriptional activation of a large number of genes, as well as to replication, silencing, and telomere structure in yeast. In spite of their widespread roles in transcription, the scope of their functional targets genome-wide has not been previously determined. We have used microarrays to examine the contribution of these essential GRFs to transcription genome-wide, by using ts mutants that dissociate from their binding sites at 37 C. more...

(Submitter supplied) In yeast, ribosome production is controlled transcriptionally by tight coregulation of the 138 ribosomal protein genes (RPGs). RPG promoters display limited sequence homology, and the molecular basis for their coregulation remains largely unknown. Here we identify two prevalent RPG promoter types, both characterized by upstream binding of the general transcription factor (TF) Rap1 followed by the RPG-specific Fhl1/Ifh1 pair, with one type also binding the HMG-B protein Hmo1. 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.

How promoter directionality is controlled remains poorly understood. We show that chromatin remodelling complex RSC, general regulatory factors (GRFs) including transcription factors (TFs) can facilitate promoter directionality by attenuating divergent noncoding transcription. more...

One copy of RAP1 is expressed from the endogenous RAP1 promoter and a c-terminal 3X FLAG epitiope tag and the other is expressed from a weakened Galactose inducible promoter and a c-terminal 9X MYC tag. Following induction by 2% galactose Rap1-Myc and Rap1-Flag levels are determined genome wide using ChIP-chip.
