UAS regulatory sequences drive expression of klu amino acid residues 350-583 which are tagged at the N-terminal end with Tag:HA followed by a nuclear localization signal (Tag:NLS(Unk)).
Expression of klu350-583.Scer\UAS.T:Ivir\HA1,T:Uuuu\nls6 under the control of Scer\GAL4klu-G410 results in the loss of bristles.
