The conserved role of the RSC chromatin remodeler in the establishment of nucleosome depleted regions

Project description:The occupancy of nucleosomes governs access to the eukaryotic genomes and results from a combination of biophysical features and the effect of ATP-dependent remodeling complexes. Most promoter regions show a conserved pattern characterized by a nucleosome-depleted region (NDR) flanked by nucleosomal arrays. The conserved RSC remodeler was reported to be critical to establish NDR in vivo in budding yeast but other evidences suggested that this activity may not be conserved in fission yeast. By reanalysing and expanding previously published data, we propose that NDR formation is dependent on RSC in both yeast species. We also discuss the most prominent biological role of RSC and the possibility that non-essential subunits define alternate versions of the complex. Samples from mononucleosomal DNA from S. pombe strains h- kanR-tetO-snf21-Tap-natR ura4::rTetR-tup11 were sequenced (Illumina NextSeq 500 platform) using the pair-end read protocol

Histone H2B ubiquitylation represses gametogenesis by opposing RSC-Dependent chromatin remodeling at the ste11 master regulator locus

Project description:Chromatin modifications play a pivotal role in cell fate decision. In fission yeast, the ste11 gene encodes the master regulator initiating the switch from vegetative growth to gametogenesis when cells starve. The methylation of H3K4 by Set1-COMPASS and consequent promoter nucleosome deacetylation was shown to repress ste11 induction and cell differentiation but the regulatory steps remain poorly understood. A genetic screen highlighted H2B ubiquitylation and the RSC remodeling complex as activators of ste11 expression. Mechanistic analyses revealed more complex, opposite roles of H2B-ub1 at the promoter where it represses expression, and over the transcribed region where it sustains transcription of ste11. By promoting H3K4 methylation at the promoter, H2B-ub1 initiates the deacetylation process, which decreases chromatin remodeling by RSC. Upon induction, this process is reversed and efficient NDR formation leads to high expression. Therefore, H2B-ub1 represses gametogenesis by opposing the recruitment of RSC at the promoter of the master regulator ste11 gene. Samples from mononucleosomal DNA from S. pombe strains h-972 and h-972 rsc1::kanR were sequenced (Illumina NextSeq 500 platform) using the pair-end read protocol
