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.
Publication
Antagonism of Chk1 signaling in the G2 DNA damage checkpoint by dominant alleles of Cdr1.
Activation of the Chk1 protein kinase by DNA damage enforces a checkpoint that maintains Cdc2 in its inactive, tyrosine-15 (Y15) phosphorylated state. Chk1 downregulates the Cdc25 phosphatases and concomitantly upregulates the Wee1 kinases that control the phosphorylation of Cdc2. Overproduction of Chk1 causes G(2) arrest/delay independently of DNA damage and upstream checkpoint genes. We utilized this to screen fission yeast ... [more]

| CHK1 WEE1 | Biochemical Activity Biochemical Activity An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation. | Low | - | BioGRID | 250562 | |
