Mutation in destruction box D2 (amino acid replacements R131A and L134A).
Expression of vihmD2.Scer\UAS.P\T under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 in a wild-type or background has no phenotypic effect, although expression of vihmD2.Scer\UAS.P\T under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 in a vih+/vih- background results in sterility in some females.
