Drives expression in the dorsal ectoderm of embryos, in developing posterior spiracles, and at the anterior-posterior compartment boundary of the wing disc.
Expressed in spiracular branch 10 and posterior spiracle beginning at stage 12, continuing through stage 17, and cells of the dorsal ectoderm.
ScerGAL4dpp.PS drives expression along the lateral edges of the eye disc, and in a stripe medially across the antennal disc, roughly parallel to the morphogentic furrow of the eye disc.
ScerGAL4dpp.PS drives expression The P{dpp-GAL4.PS}6A insertion drives expression only in the posterior spiracles at embryonic stage 17. The P{dpp-GAL4.PS}s(3)4B4B and P{dpp-GAL4.PS}l(3)8B8B insertions additionally drive expression starting at embryonic stage 12, in a subset of leading edge cells of the dorsal ectoderm and a cluster of posterior dorsal ectoderm cells, then in the posterior spiracle primordium.
