A novel role of the N terminus of budding yeast histone H3 variant Cse4 in ubiquitin-mediated proteolysis.

ABSTRACT: Regulating levels of centromeric histone H3 (CenH3) variant is crucial for genome stability. Interaction of Psh1, an E3 ligase, with the C terminus of Cse4 has been shown to contribute to its proteolysis. Here, we demonstrate a role for ubiquitination of the N terminus of Cse4 in regulating Cse4 proteolysis for faithful chromosome segregation and a role for Doa1 in ubiquitination of Cse4.
