Dosage Lethality
A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.
Publication
Genetic interactions between the ESS1 prolyl-isomerase and the RSP5 ubiquitin ligase reveal opposing effects on RNA polymerase II function.
Transcription of protein-coding genes by RNA polymerase II (pol II) is a highly coordinated process that requires the stepwise association of distinct protein complexes with the C-terminal domain (CTD) of Rpbl, the largest subunit of RNA pol II. Interaction of these complexes with the CTD might be subject to regulation by proteins such as Ess1 and Rsp5. Ess1, a prolyl-isomerase, ... [more]
