UASt regulatory sequences drive expression of X11L amino acid residues 778-1168 (the PI domain attached to the carboxy-terminal domain).
visible, with Scer\GAL4GMR.PY
eye, with Scer\GAL4GMR.PY
Expression of X11LPI+C.Scer\UAS under the control of Scer\GAL4GMR.PY results in defects in eye morphology.
