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.

Regulation of checkpoint kinases through dynamic interaction with Crb2.
ATR/Rad3-like kinases promote the DNA damage checkpoint through regulating Chk1 that restrains the activation of cyclin-dependent kinases. In fission yeast, Crb2, a BRCT-domain protein that is similar to vertebrate 53BP1, plays a crucial role in establishing this checkpoint. We report here that Crb2 regulates DNA damage checkpoint through temporal and dynamic interactions with Rad3, Chk1 and replication factor Cut5. The ... [more]
