ChIP-chip data of Npl3-Myc and Rrm3-Flag in wild-type and npl3M-bM-^HM-^F cells

ABSTRACT: Transcription is a major obstacle for replication fork progression and a cause of genome instability. Such instability increases in mutants with a suboptimal assembly of the nascent messenger ribonucleo-protein particle (mRNP), as THO/TREX and some heterogeneous nuclear ribonucleoproteins (hnRNPs) mutants. Here we show that yeast npl3M-bM-^HM-^F cells show genome-wide replication obstacles as determined by accumulation of the Rrm3 helicase. Such obstacles preferentially occur at long and highly expressed genes, to which Npl3 is preferentially bound in wild-type cells. ChIP-chip studies were perfomed with antibodies against Myc-tagged Npl3 protein in wild-type cells of the yeast S. Cerevisiae, as well as Flag-tagged Rrm3 protein in both wild-type and npl3M-bM-^HM-^F cells.

ChIP-chip data of Thp1-Flag and Sac3-Flag in wild-type cells, and Rrm3-Flag in sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells

Project description:Transcription is a major obstacle for replication fork progression and a cause of genome instability. Such instability increases in mutants with a suboptimal assembly of the nascent messenger ribonucleo-protein particle (mRNP), as THO/TREX and the NPC-associated THSC/TREX-2 complex. Here we show that yeast sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells accumulate genome-wide replication obstacles as determined by the distribution of the Rrm3 helicase. Such obstacles preferentially occur at long and highly expressed genes, to which Sac3 and its interacting partner Thp1 are preferentially bound in wild-type cells. ChIP-chip studies were perfomed with antibodies against Flag-tagged Thp1 and Sac3 proteins in wild-type cells of the yeast S. Cerevisiae, as well as Flag-tagged Rrm3 protein in sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells that were compared with Rrm3 in wild-type cells from Santos-Pereira et al., 2013 (accession number GSE50185).

The yeast and human FACT complexes resolve R-loop-mediated transcription-replication conflicts

Project description:Transcription is a major obstacle for replication fork progression and transcription-replication collisions constitute a main cause of genome instability. At a genome-wide scale these obstacles can be detected by the accumulation of the replicative Rrm3 helicase required for RF progression through protein obstacles. Here we show that FACT, a chromatin-reorganizing complex that swaps nucleosomes around the RNA polymerase during transcription elongation and that also has a role in replication, is needed to resolve transcription-replication conflicts in Saccharomyces cerevisiae. Importantly, ChIP-chip analyses of Rrm3 reveal that replication progression impairment in FACT mutants occur genome-wide, but preferentially at highly transcribed regions. ChIP-chip studies were perfomed with antibodies against Rrm3-FLAG in the yeast S. cerevisiae.

ChIP-chip data of Rrm3-Flag in wild-type and rpb1-1 cells

Project description:Transcription is a major contributor to genome instability.A main cause of transcription-associated instability relies on the capacity of transcription to stall replication. Such genome instability is increased in RNAPII mutants. ChIP-chips performed in asynchronous cultures showed an increase of the Rrm3 binding signal all over the genome in rpb1-1 compared to wild-type. ChIP-chip studies were perfomed with antibody against Flag-tagged Rrm3 protein in both wild-type and rpb1-1 cells.

Genome-wide binding of THO and Sub2 in Saccharomyces cerevisiae

Project description:THO/TREX is a conserved nuclear complex that functions in mRNP biogenesis and prevents transcription-associated recombination. Whether or not it has a ubiquitous role in the genome is an open question. ChIP-chip studies reveal that the Hpr1 component of THO and the Sub2 RNA-dependent ATPase have genome wide-distributions at active ORFs in yeast. In contrast to RNAPII, evenly distributed from promoter to termination regions, THO and Sub2 are absent at promoters and distributed in a sharp 5M-bM-^@M-^YM-bM-^FM-^R3M-bM-^@M-^Y gradient. Importantly, ChIP-chips reveal an over-recruitment of Rrm3 in active genes in THO mutants that is reduced by overexpression of RNase H1. Our work establishes a genome-wide function for THO-Sub2 in transcription elongation and mRNP biogenesis that function to prevent the accumulation of transcription-mediated replication obstacles, including R-loops. ChIP-chip studies were perfomed with tagged forms of the Hpr1 component of THO (Hpr1-FLAG), the Sub2 RNA-dependent ATPase of TREX (Sub2-FLAG), the Rpb3 subunit of RNA polymerase II (Rpb3-PK) and the Rrm3 protein (Rrm3-FLAG) in the yeast S. cerevisiae.

ChIP-chip data of HA-Yra1 and Rrm3-Flag in wild-type and cells overexpressing YRA1

Project description:Transcription is a major obstacle for replication fork progression and a cause of genome instability. Yra1 is an essential nuclear factor of the evolutionarily conserved family of hnRNP-like export factors that when overexpressed impairs mRNA export and cell growth. Through this ChIP-chip analysis it is shown that Yra1 binds to active chromatin and is enriched at telomeres when it is overexpressed, in agreement with a possible role of this mRNP factor in the maintenance of telomere integrity. Our data indicate that YRA1 overexpression correlates with replication impairment as inferred by the increase of Rrm3, a helicase involved in the replication fork progression, at transcribed genes and telomeres. ChIP-chip studies were perfomed with antibodies against HA-tagged Yra1 protein in wild-type cells and cells overexpressing YRA1 of the yeast S. Cerevisiae, as well as Flag-tagged Rrm3 protein in both wild-type and cells overexpressing YRA1.

Rad53-mediated regulation of Rrm3 and Pif1 DNA helicases contributes to prevention of aberrant fork transitions under replication stress.

Project description:Replication stress activates the Mec1ATR and Rad53 kinases. Rad53 phosphorylates nuclear pores to counteract gene gating, thus preventing aberrant transitions at forks approaching transcribed genes. Here, we show that Rrm3 and Pif1, DNA helicases assisting fork progression across pausing sites, are detrimental in rad53 mutants experiencing replication stress. Rrm3 and Pif1 ablations rescue cell lethality, chromosome fragmentation, replisome-fork dissociation, fork reversal, and processing in rad53 cells. Through phosphorylation, Rad53 regulates Rrm3 and Pif1; phospho-mimicking rrm3 mutants ameliorate rad53 phenotypes following replication stress without affecting replication across pausing elements under normal conditions. Hence, the Mec1-Rad53 axis protects fork stability by regulating nuclear pores and DNA helicases. We propose that following replication stress, forks stall in an asymmetric conformation by inhibiting Rrm3 and Pif1, thus impeding lagging strand extension and preventing fork reversal; conversely, under unperturbed conditions, the peculiar conformation of forks encountering pausing sites would depend on active Rrm3 and Pif1. BrdU incorporation profiles by ssDNA-BrdU IP on chip have been generated as described (Katou et al., 2003). Protein binding profiles by ChIP-chip analysis were generated as described (Bermejo et al., 2009). Labeled probes were hybridized to Affymetrix S.cerevisiae Tiling 1.0 (P/N 900645) arrays and processed with TAS software.

The shuttling SR-like proteins Gbp2 and Hrb1 mediate the nuclear export of spliced mRNAs

Project description:Three shuttling SR-like proteins exist in Saccharomyces cerevisiae, Npl3, Gbp2 and Hrb1, that are involved in the nuclear export of mRNAs. In a screen for genes that regulate the export of Gbp2, we identified novel mutants of the splicing factors PRP8 and PRP17 that lead to severe mislocalization defects for Gbp2 and Hrb1, but not Npl3. Microarray and qRT-PCR analyses show that Gbp2 and Hrb1 preferentially bind to transcripts derived from intron-containing genes. Moreover, in contrast to Npl3, Gbp2 and Hrb1 show genetic and physical interactions with late splicing factors such as Prp17 and Prp43. Further, RNA co-immunoprecipitation experiments reveal that, unlike Npl3, association of Gbp2 and Hrb1 with the mRNA requires splicing, and this in turn is required for their Mex67 recruitment. We propose a model in which Gbp2 and Hrb1 are attached to the mRNAs at late stages of splicing to promote the subsequent export of spliced mRNAs. keyword: RIP-chip RNA-IP of endogenously expressed 3-fold C-terminal myc-tagged Gbp2 and Hrb1 in S288C background cells was each performed once in cells grown to a density of 4x10^7 cells/ml and hybridized against a total (input) RNA reference.
