UASt regulatory sequences drive expression of a mutant form of Hsap\MAPT : Hsap\MAPTR406W.UAS has been further mutated to include the C291A and C322A mutations.
Expression of Hsap\MAPTC2A.Scer\UAS under the control of Scer\GAL4GMR.PU results in a rough eye phenotype, but this is milder than the phenotype seen in flies expressing Hsap\MAPTR406W.Scer\UAS. Expression under the control of Scer\GAL4elav.PU reduces lifespan, but less severely then in Hsap\MAPTR406W.Scer\UAS mutants. Far fewer vacuoles are also seen. Neither the lifespan or the vacuoles are altered by feeding the flies ZnCl[[2]].
