CLB3

B-type cyclin CLB3, L000000351, YDL155W
B-type cyclin involved in cell cycle progression; activates Cdc28p to promote the G2/M transition; may be involved in DNA replication and spindle assembly; accumulates during S phase and G2, then targeted for ubiquitin-mediated degradation; relative distribution to the nucleus increases upon DNA replication stress; CLB3 has a paralog, CLB4, that arose from the whole genome duplication

MAD2

spindle checkpoint protein MAD2, L000000975, YJL030W
Component of the spindle-assembly checkpoint complex; delays onset of anaphase in cells with defects in mitotic spindle assembly; forms a complex with Mad1p; regulates APC/C activity during prometaphase and metaphase of meiosis I; gene dosage imbalance between MAD1 and MAD2 leads to chromosome instability

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Specific genetic interactions between spindle assembly checkpoint proteins and B-Type cyclins in Saccharomyces cerevisiae.

Ikui AE, Cross FR

The B-type cyclin Clb5 is involved primarily in control of DNA replication in Saccharomyces cerevisiae. We conducted a synthetic genetic array (SGA) analysis, testing for synthetic lethality between the clb5 deletion and a selected 87 deletions related to diverse aspects of cell cycle control based on GO annotations. Deletion of the spindle checkpoint genes BUB1 and BUB3 caused synthetic lethality ... [more]

Ontology Terms

  • phenotype: inviable (APO:0000112)
  • phenotype: spindle morphology (APO:0000213)

Additional Notes

  • The clb3 clb4 mad2 triple mutant has defects in spindle pole body separation and spindle assembly.
  • This is a clb3 clb4 mad2 triple mutant. MAD2 was found to be essential in the absence of CLB3 and CLB4.
