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

MUB1

L000004359, YMR100W
MYND domain-containing protein; required for ubiquitination and turnover of Rpn4p; interacts with Ubr2p (E3) and indirectly with Rad6p (E2); short-lived protein degraded in a Ubr2p/Rad6p dependent manner; similar to the A. nidulans samB gene

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

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]

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.
