UAS regulatory sequences drive expression of an Aβ peptide (11-42). The Hsap\APP sequence in the construct is codon-optimized for expression in Drosophila melanogaster. A consensus Drosophila melanogaster translation start site is used. The signal sequence used in the construct is Tag:SS(rPENK).
Compared with wild-type, flies expressing Scer\GAL4nSyb.PS>Hsap\APP11-42.Scer\UAS.T:Rnor\SS-PENK have strongly reduced median lifespan.
Flies expressing Scer\GAL4nSyb.PS>Hsap\APP11-42.Scer\UAS.T:Rnor\SS-PENK display locomotor dysfunction.
