Abstract excerpt
Bleomycin is an antitumor drug that kills cells by introducing lesions in DNA. Thus, normal cells exposed to bleomycin must rely on efficient DNA repair mechanisms to survive. In the yeast Saccharomyces cerevisiae, the transcriptional activator Imp2 is required to fend off the toxic effects of bleomycin. However, it remains unclear whether Imp2 controls the expression of a protein that either repairs...
