Top-SUMO wrestles centromeric cohesion.
Sister chromatid cohesion at the centromere is distinct from cohesion at the chromosome arms. In the June issue of Molecular Cell, Bachant et al. have shown that centromeric cohesion in budding yeast is specifically regulated by SUMO-1 modification of Topoisomerase II.
