UAS regulatory sequences drive expression of 103 pure repeats of Zzzz\GGGGCC.
Constitutive expression of Zzzz\GGGGCC103.Scer\UAS in the eye using Scer\GAL4GMR.PU causes eye degeneration. Increasing expression levels of the pure repeats by increasing the temperature leads to lethality.
Adult-onset expression of Zzzz\GGGGCC103.Scer\UAS under the control of Scer\GAL4elav.Switch.PO (in combination with RU486 treatment) kills all flies by 30 days after eclosion.
