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
Fission yeast Ubr1 ubiquitin ligase influences the oxidative stress response via degradation of active Pap1 bZIP transcription factor in the nucleus.
Cells adapt to oxidative stress by transcriptional activation of genes encoding antioxidants and proteins of other protective roles. A bZIP transcription factor, Pap1, plays a critical role in this process and overexpression of Pap1 confers resistance to various oxidants and drugs in fission yeast. Pap1 temporarily enters the nucleus upon oxidative stress but returns to the cytoplasm once cells adapt ... [more]
