摘要

In Saccharomyces cerevisiae, the overexpression of ROD1 confers resistance to o-dinitrobenzene (o-DNB), a representative of target drugs of glutathione S-transferase. The roles of Rod1 in drug resistance have remained to be determined. We isolated the rog3 mutation as a suppressor mutation of the temperature sensitivity of the strain, in that two of the total four glycogen synthase kinase 3 homologs were deleted. Rog3 is homologous to Rod1, and its overexpression also conferred resistance to o-DNB. Furthermore, these two proteins have PY-motifs, and bound to Rsp5, a hect-type ubiquitin ligase. The rsp5-101 mutant showed sensitivity to o-DNB as did the rod1 mutant, a mutant Rod1 containing altered PY motifs was defective in ability to bind to Rsp5 and in conferring o-DNB resistance. These results suggest that interaction of Rod1 and Rsp5 is important for drug resistance.
