Enhancer trap expression is evidentposterior to the morphogenetic furrow. Expression is also observed inBolwig's organ in the late embryo and in some cells of the embryonic andthird-instar larval brain.
Expression in cells posterior to themorphogenetic furrow in eye-antennal disc, in Bolwig's organ in lateembryos, and in some cells of the embryonic and larval brain. Noexpression observed in adult head.
The position of the P{lacW} insertion lies between 3148bp and 2068bp 5' to the gl transcription start site.
