A diagram of the PBac{3HPy+} element is available at the [GDP Transposons page](http://flypush.imgen.bcm.tmc.edu/pscreen/transposons.html)
The PBac{3HPy+} transgene is a Tni\piggyBac element into which a y+mDint2 marker and a P-element 3' terminus have been inserted, disrupting the Tni\piggyBac\T transposase gene. The inserted sequences are in the opposite orientation to the direction of transcription of Tni\piggyBac\T.
