UAS regulatory sequences drive expression of two copies of a 125bp AAGAG repeat sequence in an inverted repeat.
Expression of Zzzz\AAGAGdsRNA.Scer\UAS.Sym under the control of Scer\GAL4αTub84B.PL or Scer\GAL4Act5C.PI results in larvae that initiate pupation but fail to progress to transformation for several days, eventually leading to death and degradation.
