PDS1

securin, L000001368, YDR113C
Securin; inhibits anaphase by binding separin Esp1p; blocks cyclin destruction and mitotic exit, essential for meiotic progression and mitotic cell cycle arrest; localization is cell-cycle dependent and regulated by Cdc28p phosphorylation

CLB2

B-type cyclin CLB2, L000000350, YPR119W
B-type cyclin involved in cell cycle progression; activates Cdc28p to promote the transition from G2 to M phase; accumulates during G2 and M, then targeted via a destruction box motif for ubiquitin-mediated degradation by the proteasome; CLB2 has a paralog, CLB1, that arose from the whole genome duplication

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.

APC(Cdc20) promotes exit from mitosis by destroying the anaphase inhibitor Pds1 and cyclin Clb5.

Shirayama M, Toth A, Galova M, Nasmyth K

Ubiquitin-mediated proteolysis due to the anaphase-promoting complex/cyclosome (APC/C) is essential for separation of sister chromatids, requiring degradation of the anaphase inhibitor Pds1, and for exit from mitosis, requiring inactivation of cyclin B Cdk1 kinases. Exit from mitosis in yeast involves accumulation of the cyclin kinase inhibitor Sic1 as well as cyclin proteolysis mediated by APC/C bound by the activating subunit ... [more]
