1 Yap1 overproduction restores arsenite resistance to the ABC transporter deficient mutant ycf1 by activating ACR3 expression. arsenite Arr3p Saccharomyces cerevisiae S288C
2 Ycf1 and Acr3 are transporters that have been previously shown to protect Saccharomyces cerevisiae cells from the toxic effects of arsenite. arsenite Arr3p Saccharomyces cerevisiae S288C
3 We further show that the expression of either an ACR3-lacZ promoter fusion reporter or the endogenous ACR3 gene was stimulated by the overproduction of Yap1 upon exposure to arsenite. arsenite Arr3p Saccharomyces cerevisiae S288C
4 We further show that the expression of either an ACR3-lacZ promoter fusion reporter or the endogenous ACR3 gene was stimulated by the overproduction of Yap1 upon exposure to arsenite. arsenite Arr3p Saccharomyces cerevisiae S288C
5 These data suggest that Yap1 confers arsenite resistance to the ycf1 null mutant by activating expression of the Yap8-dependent target gene, ACR3. arsenite Arr3p Saccharomyces cerevisiae S288C
6 Our data also show Yap8-dependent ACR3-lacZ expression was greatly stimulated by arsenite in a dose-dependent manner in the parental strain. arsenite Arr3p Saccharomyces cerevisiae S288C
