UAS regulatory sequences drive expression of the Hsap\MAPT 2N4R isoform, with S-to-E amino acid replacements in 6 residues to mimic phosphorylation by Hsap\TTBK1 (S198E, S199E, S202E, S208E, S210E, S422E).
Expression of Hsap\MAPTTTBK1S6E.Scer\UAS.2N4R under the control of Scer\GAL4nSyb.PS combined with tub-Gal800[ts] to limit the expression to adulthood does not have a significant effect on the adult lifespan.
