5 copies of UAS regulatory sequences drive expression of a mutant Aβ1-42 peptide of Hsap\APP with three histidines (His 6, 13 and 14 of the metal binding site) changed into arginines.
visible, with Scer\GAL4GMR.PF
eye, with Scer\GAL4GMR.PF
Expression of Hsap\APP3HR.attB.Aβ42.Scer\UAS under the control of Scer\GAL4GMR.PF causes only mild eye degeneration, which can not be exacerbated by feeding the flies extra zinc.
