Mutation in destruction boxes D1 and D2 (amino acid replacements R82A, L85A, R131A and L134A). The protein is tagged with Tag:polyHis.
Expression of vihmD1D2.Scer\UAS.P\T.T:Zzzz\His6 under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 in a wild-type or background has no phenotypic effect, although expression of vihmD1D2.Scer\UAS.P\T.T:Zzzz\His6 under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 in a vih+/vih- background results in female sterility.
