Role for cohesin in the formation of a heterochromatic domain at fission yeast subtelomeres.

ABSTRACT: Increasing evidence implicates cohesin in the control of gene expression. Here we report the first analysis of cohesin-dependent gene regulation in fission yeast. Global expression profiling of the mis4-367 cohesin loader mutant identified a small number of upregulated and downregulated genes within subtelomeric domains (SD). These 20- to 40-kb regions between chromosome arm euchromatin and telomere-proximal heterochromatin are characterized by a combination of euchromatin (methylated lysine 4 on histone H3/methylated Tysine 9 on histone H3 [H3K4me]) and heterochromatin (H3K9me) marks. We focused our analysis on the chromosome 1 right SD, which contains several upregulated genes and is bordered on the telomere-distal side by a pair of downregulated genes. We find that the expression change
