Genome-wide maps of chromatin state (centromeric histone H3 variant CENP-A/Cnp1) in clr4? and the transformants from the deletion of clr4 in mhf2? (cen2_inactive) or mhf2+ (cen1_inactive).

We report the high-throughput profiling of histone variant CNEP-A/Cnp1 in fission yeast Schizosaccharomyces pombe. By obtaining 1-10 ng immunoprecipitated DNA, we generated genome-wide CENP-A/Cnp1 maps of clr4? and the transformants from the deletion of clr4 in mhf2? (cen2_inactive) or mhf2+ (cen1_inactive) in fission yeast. We find that heterochromatin is not required for the induction of centromere inactivation in mhf2? and the maintenance of neocentromere in mhf2+. Overall design: Only one biological replicate of these strains were examined by anti-CENP-A/Cnp1 ChIP-seq.
