Project description:Genome wide map of heterochromatin state in fission yeast Schizosaccharomyces pombe via 4 different strains Examination of a single histone modification in 4 different fission yeast strains
Project description:Here, we report the high-throughput profiling of histone modification (H3K9me2) in fission yeast Schizosaccharomyces pombe. We generated genome-wide H3K9me2 maps of fission yeast mutants in swo1-26 (temperature sensitive, ts) cells at 25℃ and 37℃. We find that H3K9me2 enrichment at heterochromatin regions, especially at the mating-type locus and subtelomeres, is compromised, suggesting heterochromatin assembly defects.
Project description:Hrp3_Purification from Schizosaccharomyces pombe 972h- Eukaryotic genome is composed of repeating units of nucleosomes to form chromatin arrays. A canonical gene is marked by nucleosome free region (NFR) at its 5’ end followed by uniformly spaced arrays of nucleosomes. In fission yeast we show both biochemically and in vivo that both Hrp1 and Hrp3 are key determinants of uniform spacing of genic arrays.
