(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) In this study, we elucidate the common logic of the RPGs regulatory network by evaluating both the architecture and activity of promoters under conditions of stress or modulation of TF levels, and we identified the proteins regulating the activity of promoters lacking Rap1 binding, thus demonstrating that RPG co-regulation requires the complementary action of two different mechanisms involving both Ifh1 and Sfp1.

(Submitter supplied) Previous studies indicate that eukaryotic promoters display a stereotypical chromatin landscape characterized by a well-positioned +1 nucleosome near the transcription start site and an upstream -1 nucleosome that together demarcate a nucleosome-free (or depleted) region. Here we present evidence that there are two distinct types of promoters distinguished by the resistance of the -1 nucleosome to micrococcal nuclease digestion. 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) 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) 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) Transcriptional regulation of the Saccharomyces cerevisiae HO gene is highly complex, requiring a balance of multiple activating and repressing factors to ensure that only a few transcripts are produced in mother cells within a narrow window of the cell cycle. Here, we show that the Ash1 repressor associates with two DNA sequences that are usually concealed within nucleosomes in the HO promoter and recruits the Tup1 corepressor and the Rpd3 histone deacetylase, both of which are required for full repression in daughters. more...

(Submitter supplied) The majority of Saccharomyces cerevisiae snoRNA promoters contain an aRCCCTaa sequence motif located at the upstream border of a TATA-containing nucleosome-free region. Genome-wide ChIP-seq analysis showed that these motifs are bound in vivo by Tbf1, a telomere-binding protein known to recognize mammalian-like T2AG3 repeats at sub-telomeric regions. Tbf1 has over 100 additional promoter targets, including the TBF1 gene itself. more...
