(Submitter supplied) A strain harboring two copies of RAP1 is used for a competition-ChIP experiment. 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.

(Submitter supplied) Organisms respond to changes in their environment, and many such responses are initiated at the level of gene transcription. Here, we provide evidence for a previously undiscovered mechanism for directing transcriptional regulators to new binding targets in response to an environmental change. We show that Rap1, a master regulator of yeast metabolism, binds to an expanded target set upon nutrient depletion despite decreasing protein levels and no evidence of posttranslational modification. 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) 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) The classic view of nucleosome organization at active promoters is that two well-positioned nucleosomes flank a nucleosome-depleted region (NDR). However, this view has been recently challenged by contradictory reports as to whether a distinct set of wider (≳150 bp) NDRs instead contain unusually unstable Micrococcal Nuclease-sensitive “fragile” particles, thought to be nucleosomal because of their size. more...

(Submitter supplied) DNA topoisomerases are known to promote transcription in prokaryotes by removing excessive DNA supercoils produced during elongation. However, it is unclear how topoisomerases in eukaryotes are recruited and function in the transcription pathway in the context of nucleosomes. To address this problem we present high-resolution genome wide maps of one of the major eukaryotic topoisomerases, Topoisomerase II (Top2) and nucleosomes in the budding yeast, Saccharomyces cerevisiae. more...

(Submitter supplied) This is the microarray data accompanying the aforementioned manuscript. Summary: The histone chaperone Vps75 forms a complex with, and stimulates the activity of, the histone acetyltransferase Rtt109. However, Vps75 can also be isolated on its own and might therefore play a role in histone-related cellular processes independently of Rtt109. Using the E-MAP approach, we compared the genetic interaction profiles for VPS75 and RTT109 and found that, whereas deletion of RTT109 behaved like DNA replication/repair mutants, vps75Δ genetically interacted with genes linked to transcriptional regulation. more...

(Submitter supplied) Binding of transcription factors to DNA is a key regulatory step in the control of gene expression. DNA sequences with high affinity for transcription factors occur more frequently in the genome than instances of genes bound or regulated by these factors. Although several mechanisms have been identified that influence the specificity of transcriptional regulation, it is not known if these can explain the observed genome-wide pattern of binding or regulation for a given transcription factor. more...

(Submitter supplied) Binding of transcription factors to DNA is a key regulatory step in the control of gene expression. DNA sequences with high affinity for transcription factors occur more frequently in the genome than instances of genes bound or regulated by these factors. How specific gene regulation is achieved by transcription factors remains unclear. We used genome-wide approaches to study how trans factors shape the binding and regulatory landscape of Pho4, a budding yeast transcription factor that activates gene expression in response to phosphate limitation. more...

(Submitter supplied) Precise gene expression patterns are established by timely and specific binding of transcription factors (TFs) to regulatory sequences. While these events occur in the context of chromatin, our understanding of how TF-nucleosome interplay affects gene expression is highly limited. Here we present a novel assay for high-resolution measurements of both DNA occupancy and gene expression on large-scale libraries of systematically designed regulatory sequences. more...

(Submitter supplied) Chromatin plays roles in processes governed by different time scales. To assay the dynamic behaviour of chromatin in living cells, we used genomic tiling arrays to measure histone H3 turnover in G1-arrested S. cerevisiae at single-nucleosome resolution over 4% of the genome, and over the entire genome at lower (~265 bp) resolution. We find that nucleosomes at promoters are replaced more rapidly than at coding regions, and that replacement rates over coding regions correlate with polymerase density. more...
