Native elongating transcript sequencing (NET-seq) of wild type Saccharomyces cerevisiae and of DST1, RCO1, SET1, SET2, EAF3 deletion strains

Project description:We present an approach (native elongating transcript sequencing, NET-seq), based on deep sequencing of 3M-bM-^@M-^Y ends of nascent transcripts associated with RNA polymerase, to monitor transcription at nucleotide resolution. Application of NET-seq in Saccharomyces cerevisiae reveals that while promoters are generally capable of divergent transcription, the Rpd3S deacetylation complex enforces strong directionality to most promoters by suppressing antisense transcript initiation. Our studies also reveal pervasive polymerase pausing and backtracking throughout the body of transcripts. Average pause density shows prominent peaks at each of the first four nucleosomes, with the peak location occurring in good agreement with in vitro biophysical measurements. Thus nucleosome-induced pausing represents a major barrier to transcriptional elongation in vivo. Examination of nascent transcripts in yeast and mutant strains

Native elongating transcript sequencing (NET-seq) of wild type Saccharomyces cerevisiae and of DST1, RCO1, SET1, SET2, EAF3 deletion strains

Project description:We present an approach (native elongating transcript sequencing, NET-seq), based on deep sequencing of 3’ ends of nascent transcripts associated with RNA polymerase, to monitor transcription at nucleotide resolution. Application of NET-seq in Saccharomyces cerevisiae reveals that while promoters are generally capable of divergent transcription, the Rpd3S deacetylation complex enforces strong directionality to most promoters by suppressing antisense transcript initiation. Our studies also reveal pervasive polymerase pausing and backtracking throughout the body of transcripts.

RNA binding by the histone methyltransferases Set1 and Set2

Project description:Histone methylation at H3K4 and H3K36 is commonly associated with genes actively transcribed by RNA polymerase II (RNAPII) and is catalyzed by Saccharomyces cerevisiae Set1 and Set2, respectively. Here we report that both methyltransferases can be UV cross-linked to RNA in vivo. High-throughput sequencing of the bound RNAs revealed strong Set1 enrichment near the transcription start site, whereas Set2 was distributed along pre-mRNAs. A subset of transcripts showed notably high enrichment for Set1 or Set2 binding relative to RNAPII, suggesting functional post-transcriptional interactions. In particular, Set1 was strongly bound to the SET1 mRNA, Ty1 retrotransposons, and noncoding RNAs from the ribosomal DNA (rDNA) intergenic spacers, consistent with its previously reported silencing roles. Set1 lacking RNA recognition motif 2 (RRM2) showed reduced in vivo cross-linking to RNA and reduced chromatin occupancy. In addition, levels of H3K4 trimethylation were decreased, whereas levels of dimethylation were increased. We conclude that RNA binding by Set1 contributes to both chromatin association and methyltransferase activity.

TEF-seq/NET-seq applied to factors Rpb3, Paf1, Spt6, Spt16, Cet1, Pcf11, Ssu72, Set2

Project description:Here we adapt native elongating transcript sequencing (NET-seq) to develop transcription elongation factor associated nascent elongating transcript sequencing (TEF-seq). In this the RNA polymerase II (Pol2) transcription elongation complex (TEC) is immunoprecipitated via associated transcription elongation factors (TEFs). Sequencing from the 3' end of the Pol2-associated nascent transcript shows the position of the final incorporated nucleotide giving strand-specific, single nucleotide resolution maps of the level of TEF association with Pol2 during transcription.

Phosphorylation of methyltransferase Set2p and demethylase Jhd1p and its association with histone H3K36 methylation and stress response pathways in Saccharomyces cerevisiae

Project description:Histone lysine methylation is a key epigenetic modification that regulates eukaryotic transcription. In Saccharomyces cerevisiae, it is controlled by a reduced but evolutionarily conserved suite of methyltransferase (Set1p, Set2p, Dot1p, and Set5p) and demethylase (Jhd1p, Jhd2p, Rph1p, and Gis1p) enzymes. Many of these enzymes are extensively phosphorylated in vivo; however, the functions of specific phosphosites are poorly understood. Here, we comprehensively investigate the phosphoregulation of the yeast histone methylation network by analysing 40 phosphosites on six enzymes through mutagenesis. A total of 82 genomically-edited S. cerevisiae strains were generated and screened for changes in native H3K4, H3K36, and H3K79 methylation levels, and for sensitivity to environmental stress conditions. This demonstrated the functional relevance of phosphosites on methyltransferase Set2p (S6, S8, S10, and T127) and demethylase Jhd1p (S44) in the regulation of H3K36 methylation in vivo, and in the coordination of specific stress response pathways in budding yeast. Proteomic analysis of SET2 mutants revealed that phosphorylation site mutations lead to significant downregulation of membrane-associated proteins and processes, consistent with changes brought about by SET2 deletion. This study represents the first systematic investigation into the phosphoregulation of an entire epigenetic network in any eukaryote, and our findings establish phosphorylation as an important regulator of histone lysine methylation in S. cerevisiae.
