ESP1

L000000584, YGR098C
Separase, a caspase-like cysteine protease; promotes sister chromatid separation by mediating dissociation of the cohesin Scc1p from chromatin; inhibits protein phosphatase 2A-Cdc55p to promote mitotic exit; inhibited by Pds1p; relative distribution to the nucleus increases upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

CDC14

OAF3, phosphoprotein phosphatase CDC14, L000000254, YFR028C
Protein phosphatase required for mitotic exit; required for rDNA segregation, cytokinesis, meiosis I spindle disassembly, and environmental stress response; maintained in nucleolus by Cdc55p in early meiosis until liberated by the FEAR and Mitotic Exit Network in anaphase, enabling it to effect a decrease in CDK/B-cyclin activity and mitotic exit; sequestered in metaphase II, then released again upon entry into anaphase II
Kinome Project (Sc)
Saccharomyces cerevisiae (S288c)

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Pds1 and Esp1 control both anaphase and mitotic exit in normal cells and after DNA damage.

Tinker-Kulberg RL, Morgan DO

The separation of sister chromatids in anaphase is followed by spindle disassembly and cytokinesis. These events are governed by the anaphase-promoting complex (APC), which triggers the ubiquitin-dependent proteolysis of key regulatory proteins: anaphase requires the destruction of the anaphase inhibitor Pds1, whereas mitotic exit requires the destruction of mitotic cyclins and the inactivation of Cdk1. We find that Pds1 is ... [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.
