Abstract excerpt
Post-translation modification through the SUMO pathway is cell cycle regulated, with specific SUMO conjugates accumulating in mitotic cells. The basis for this regulation, however, and its functional significance remain poorly understood. We present evidence that in budding yeast sumoylation during mitosis may be controlled through the SUMO deconjugating enzyme Smt4/Ulp2. We isolated the polo kinase Cdc5 as an...
