A search for multicopy suppressors that rescue the imp2Δ mutant from bleomycin toxicity revealed the transcriptional activator Yap1, which can turn on many target genes such as transporters involved in regulating drug resistance. We show that YAP1 overexpression stimulated the expression of the TPO1 gene encoding a polyamine efflux pump, and that Yap1 failed to rescue the imp2Δ mutant from bleomycin toxicity in the absence of the TPO1 gene. Moreover, TPO1 overexpression, and not the related transporter gene QDR3, conferred upon the tpo1Δ imp2Δ double mutant parental resistance to bleomycin. We conclude that YAP1 overexpression rescues the imp2Δ mutant from bleomycin toxicity by triggering Tpo1 expression to expel the drug. Our data provide the first evidence that bleomycin could be a substrate for the Tpo1 efflux pump."xsd:string |
