Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

High dosage Rhp51 suppression of the MMS sensitivity of DNA structure checkpoint mutants reveals a relationship between Crb2 and Rhp51.

Smeets MF, Francesconi S, Baldacci G

BACKGROUND: In eukaryotic cells DNA structure checkpoints organize the cellular responses of DNA repair and transient cell cycle arrest and thereby ensure genomic stability. To investigate the exact role of crb2+ in the DNA damage checkpoint response, a genetic screen was carried out in order to identify suppressors of the conditional MMS sensitivity of a crb2-1 mutant. Here we report ... [more]
