UASt regulatory sequences drive expression of a 22 amino acid polyglutamine repeat (the repeat is flanked by the amino acid sequence MRSRKL at the N-terminal end and by KLRS at the C-terminal end). The Tag:MYC and Tag:FLAG tags are present at the C-terminal end of the open reading frame (immediately after the KLRS sequence).
Expression of Zzzz\CAGQ22.Scer\UAS.T:Hsap\MYC,T:Zzzz\FLAG in neurons under the control of Scer\GAL4elav-C155 has no effect on survival to adulthood.
