UAS regulatory sequences drive expression of an inverted repeat of a 593 nt fragment starting 500bp after the start codon.
lethal - all die before end of P-stage, with Scer\GAL4Act5C.PI
some die during pharate adult stage, with Scer\GAL4Act5C.PI
Scer\GAL4Act5C.PI-driven expression of jubdsRNA.C.Scer\UAS.18.1 results in pharate lethality.
