UASt regulatory sequences drive expression of a C-terminally truncated ttk69 protein (lacking amino acid residues 568-641), tagged at the N-terminal end with three copies of Tag:HA.
Expression of ttk69.ΔC568.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4hs.2sev results in a wild-type phenotype in the eye.
