UASt regulatory sequences drive expression of the Tag:SS(nec) secretory signal peptide followed by two tandem copies of the Aβ (amyloid β) monomer linked together by a 12 amino acid linker peptide. Both copies of Aβ are the 40 amino acid residue form.
Locomotor rhythm in constant darkness (DD) is comparable to controls when Hsap\APPT12.Aβ40.Scer\UAS is expressed under the control of Scer\GAL4tim.PE or Scer\GAL4P2.4.Pdf.
Flies expressing Hsap\APPT12.Aβ40.Scer\UAS under the control of Scer\GAL4GMR.PF form significant quantities of large, SDS-insoluble deposits in the head. Abundant SDS-soluble oligomeric Aβ aggregates are also present. No detectable SDS-soluble oligomeric Aβ aggregates are present.
Expression of Hsap\APPT12.Aβ40.Scer\UAS under the control of Scer\GAL4GMR.PF does not result in a detectable rough eye phenotype.
Flies expressing one copy of Hsap\APPT12.Aβ40.Scer\UAS under the control of Scer\GAL4elav-C155 do not have a significantly different life span compared to wild-type controls.
