| Research Abstract |
In the present study, we have constructed a yeast strain expressing chimeric prion protein in which prion domain of the yeast eRF3 (Sup35) was replaced by that of human PrP. Most of the modified yeast cells spontaneously transformed to [PSI^+] and the [PSI^+] transformants were returned to [psi^-] when the cells were treated with guanidine hydrochrolide. The eRF3-PrP prion had no effect on the growth of yeast cells. Thus, we confirmed that the modified [PSI^+] prion, the amyloidgenic isoform of eRF3-PrP, could be an ideal model for investigating prion disease in yeast and for screening therapeutic drugs against prion.
