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\MARK1 (S262E, S293E, S305E, S320E, S324E, S356E).
Expression of Hsap\MAPTMARK1S6E.Scer\UAS.2N4R under the control of Scer\GAL4nSyb.PS combined with tub-Gal800[ts] to limit the expression to adulthood leads to moderately but significantly reduced adult lifespan.
The reduced adult lifespan caused by expression of Hsap\TTBK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 is also exacerbated by co-expression of Hsap\MAPTTTBK1S6A.Scer\UAS.2N4R.
