(Submitter supplied) DNA replication forks that are stalled by DNA damage activate an S phase checkpoint that prevents irreversible fork arrest and cell death. The increased cell death caused by DNA damage in budding yeast cells lacking the Rad53 checkpoint protein kinase is partially suppressed by deletion of the EXO1 gene. Here,we identified that loss of the histone deacetylase complex Rpd3L promotes survival of rad53∆ cells exposed to DNA damaging agents. more...

(Submitter supplied) Understanding chromatin dynamics is a key to other related processes, including DNA replication, transcription and recombination. As a first step, recently, an increasing amount of effort has been devoted to precisely define nucleosome positioning in different organisms. The most popular method to do so is digestion by Micrococcal nuclease (MNase), nowadays followed by ultrasequencing of the generated fragments. more...

(Submitter supplied) At the end of protein-coding genes, RNA polymerase (Pol) II undergoes a concerted transition that involves 3’-processing of the pre-mRNA and transcription termination. Here we conduct a genome-wide analysis of this 3’-transition in yeast. We find that the 3’-transition globally requires the Pol II elongation factor Spt5 and factors involved in the recognition of the poly-adenylation (pA) site and in endonucleolytic RNA cleavage. more...

(Submitter supplied) Purpose: Pre-ribosomal RNA is cleaved at defined sites to release the mature ribosomal RNAs, but the functions of many ribosome biogenesis factors involved in 18S rRNA release are not known. We apply an in vivo cross-linking technique coupled with deep sequencing (CRAC) that captures transcriptome-wide interactions between the yeast PIN domain protein Utp23 and its targets in a living cell. Methods: We apply CRAC to an HTP-tagged Utp23 protein (HTP: His6 - TEV cleavage site - two copies of the z-domain of Protein A) in budding yeast. more...

(Submitter supplied) Purpose: The ability to rationally manipulate the transcriptional states of cells would be of great use in medicine and bioengineering. We have developed a novel algorithm, NetSurgeon, which utilizes genome-wide gene regulatory networks to identify interventions that force a cell toward a desired expression state. Results: We used NetSurgeon to select transcription factor deletions aimed at improving ethanol production in S. more...

We apply an in vivo cross-linking technique coupled with deep sequencing (CRAC) that captures transcriptome-wide interactions between a yeast candidate pre-rRNA endonuclease (Utp24) and its targets in a living cell.

(Submitter supplied) Antisense long non-coding (aslnc)RNAs represent a substantial part of eukaryotic transcriptomes that are, in yeast, controlled by the Xrn1 exonuclease. Nonsense-Mediated Decay (NMD) destabilizes the Xrn1-sensitive aslncRNAs (XUT), but what determines their sensitivity remains unclear. We report that 3’ single-stranded (3’-ss) extension mediates XUTs degradation by NMD, assisted by the Mtr4 and Dbp2 helicases. more...

(Submitter supplied) Yeast chromosome III contains the mating type loci that provide a paradigm for long-range interactions between distant loci. Yeast switch mating type by gene conversion between the MAT locus and either of two silent loci (HML or HMR) on opposite ends of the chromosome. This long-range process is mating type-specific so that MATa cells choose HML as template, while MATα cells use HMR. The Recombination Enhancer (RE), located on the left arm regulates this process. more...

(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...

(Submitter supplied) We generated S.cerevisiae strains in which endogenous copies of candidate nucleosome spacing factors were replaced with the K.lactis copies. With this candidate approach, we found that K.lactis Chd1 directed longer nucleosome repeat length in S.cerevisiae. Generating chimeric proteins revealed that the strongest contribution to this differential spacing lies in the undercharacterised N-terminus of Chd1.

(Submitter supplied) The histone variant H2A.Z, which has been reported to have both activating and repressive effects on gene expression, is known to occupy nucleosomes at the 5’ ends of protein-coding genes. We now find that H2A.Z is also significantly enriched in gene coding regions and at the 3’ ends of genes in budding yeast, where it co-localises with histone marks associated with active promoters. By comparing H2A.Z binding to global gene expression in budding yeast strains engineered so that normally unstable transcripts are abundant, we show that H2A.Z is required for normal levels of antisense transcripts as well as sense ones. more...

(Submitter supplied) We have analysed the activity of the nuclear exosome during meiosis by deletion of TRF4, which encodes a key component of the exosome targeting complex TRAMP. We find that TRAMP mutants produce high levels of CUTs during meiosis that are undetectable in wild-type cells, showing that the nuclear exosome remains functional for CUT degradation. Lack of TRAMP activity stabilises ~1600 CUTs in meiotic cells, which occupy 40% of the binding capacity of the nuclear cap binding complex (CBC).

(Submitter supplied) The C-terminal domain (CTD) of the largest subunit of RNA polymerase II (RNAP II) consists of repeated YSPTSPS heptapeptides and connects transcription with cotranscriptional events. Threonine-4 (Thr4) of the CTD repeats has been shown to function in histone mRNA 3'-end processing in chicken cells and in transcriptional elongation in human cells. Here, we demonstrate that, in budding yeast, Thr4, although dispensable for growth in rich media, is essential in phosphate-depleted or galactose-containing media. more...

We mapped 23 mRNP biogenesis factors onto the newly synthesized yeast transcriptome, providing ~10^5-10^6 high-confidence RNA interaction sites per factor.
