DOA1

UFD3, ZZZ4, L000002961, YKL213C
WD repeat protein required for ubiquitin-mediated protein degradation; forms a complex with Cdc48p; plays a role in controlling cellular ubiquitin concentration; also promotes efficient NHEJ in postdiauxic/stationary phase; facilitates N-terminus-dependent proteolysis of centromeric histone H3 (Cse4p) for faithful chromosome segregation; protein increases in abundance and relocalizes from nucleus to nuclear periphery upon DNA replication stress

CSE4

CSL2, centromeric DNA-binding histone H3-like protein CSE4, L000002719, YKL049C
Centromere protein that resembles histone H3; associated with promoters, accessible chromatin and RNA polymerase II-bound regions; phosphorylated Cse4p associates with centromeres; required for proper kinetochore function; levels regulated by E3 ubiquitin ligase Psh1p; phosphorylation of Cse4p may destabilize defective kinetochores to promote bi-orientation; ubiquitination of N terminus regulates Cse4p proteolysis for faithful chromosome segregation; human CENP-A homolog

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

A Novel Role of the N-Terminus of Budding Yeast Histone H3 Variant Cse4 in Ubiquitin-Mediated Proteolysis.

Au WC, Dawson AR, Rawson DW, Taylor SB, Baker RE, Basrai MA

Regulating levels of centromeric histone H3 variant (CenH3) 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 its proteolysis for faithful chromosome segregation and a role for Doa1 in ubiquitination of ... [more]
