CBF1

CEP1, CPF1, CP1, L000000311, L000000401, YJR060W
Basic helix-loop-helix (bHLH) protein; forms homodimer to bind E-box consensus sequence CACGTG present at MET gene promoters and centromere DNA element I (CDEI); affects nucleosome positioning at this motif; associates with other transcription factors such as Met4p and Isw1p to mediate transcriptional activation or repression; associates with kinetochore proteins, required for chromosome segregation; protein abundance increases in response to DNA replication stress

DSN1

MIND complex subunit DSN1, L000004645, YIR010W
Essential component of the MIND kinetochore complex; joins kinetochore subunits contacting DNA to those contacting microtubules; phosphorylation of Dsn1p promotes interaction between outer and inner kinetochore proteins; N-terminal end interacts with monopolin subunit Csm1p and is essential for meiotic but not mitotic chromosome segregation; important for chromosome segregation; complex consists of Mtw1p Including Nnf1p-Nsl1p-Dsn1p (MIND); modified by sumoylation

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

Defects in methylation of arginine 37 on CENP-A/Cse4 are compensated by the ubiquitin ligase complex Ubr2/Mub1.

Samel A, Nguyen TKL, Ehrenhofer-Murray AE

The kinetochore, a supramolecular protein complex, provides the physical connection between chromatin and the microtubule and ensures correct chromosome segregation during mitosis. Centromeric regions are marked by the presence of the histone H3 variant CENP-A. Cse4, the CENP-A homologue from Saccharomyces cerevisiae, is methylated on arginine 37 in its N-terminus (R37), and the absence of methylation (cse4-R37A) causes synthetic genetic ... [more]

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
