Contains 2 copies of a 700bp tra2 fragment in sense-sense arrangement. The fragment encompasses most of exons 6 and 7, and contains about half of the coding region and 297bp of the 3' UTR. The two copies are separated by 42bp of vector polylinker sequence and flanked by UASt sequences on one side and a polyadenylation signal and transcription terminator in the other.
tra22xS.Scer\UAS driven under the control of Scer\GAL4Act5C.PP has no detectable effect on mutant flies. The addition of tra22xAS.Scer\UAS also had no effect.
