Project description:The aim was to compare the levels of histone H3 dimethylation at lysine 9 (H3K9me2) in wild-type and dbl2 knock-out Schizosaccharomyces pombe cells. Fission yeast cultures were grown in the complex YES medium to exponential phase and chromatin immunoprecipitation was carried out using anti-H3 and anti-H3K9me2 antibodies. Two independent biological replicates were performed. The resulting IP and input DNA samples were sequenced using Illumina sequencing (35 nt PE). H3K9me2 occupancy in each sample was normalized to the corresponding total H3 occupancy, and normalized H3K9me2 levels were compared between WT and dbl2 knock-out.
Project description:ChIP-chip analyses of H3K9me2 (in WT, erh1â??, mmi1â?? and ccr4â??), Erh1-GFP (in WT and mmi1â??) and CFP-Mmi1 (in WT) H3K9me2: WT vs erh1â??, WT vs mmi1â?? and WT vs ccr4â??; Erh1-GFP: WT vs mmi1â??; CFP-Mmi1 in WT, Biological replicates: 2
Project description:We have performed a genome wide investigation for the binding locations of the transcriptional co-repressor proteins Ssn6, Tup11 and Tup12 in the fission yeast Schizosaccharomyces pombe. We have used a ChIP protocol described previously (Robyr et al, 2003) with microarrays containing ORF and IGR fragments representing the complete fission yeast genome (Wiren et al, 2005). Keywords: ChIP-CHIP

Project description:We report the high-throughput profiling of H3K9me2 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide H3K9me2 maps in single deletions of the selected chromatin modulating genes, histone H3 mutants and ccp1Δepe1Δ double mutant in fission yeast. We find that the subtelomeric heterochromatin distribution is highly variable under different genetic perturbations and small heterochromatin islands are formed at clr4 and clr2 loci in ccp1Δepe1Δ.
