UASt regulatory sequences drive expression of an inverted repeat.
Expression of DKK103119 under the control of Scer\GAL4Fas3-NP1233 does not affect the formation of dpn ase neuroblasts in the distal inner proliferation center (d-IPC) of the optic lobe, and has no effect on distal cell specification. ato dac neuroblasts fail to form and lobular plate neurons are absent. The remaining neuroblasts in the d-IPC are no longer arranged in a crescent, instead forming a disk.
Expression of DKK103119 under the control of Scer\GAL4Bx-MS1096 results in female flies with weak wing size and patterning defects.
