UASt regulatory sequences drive expression of an inverted repeat.
Expressing RetKK107206 under the control of Scer\GAL4Ret.P2 leads to missing or shortened frontal nerves as well as disrupted frontal ganglia and esophageal ganglia that do not migrate as far as in the control.
Expression of RetKK107206 under the control of Scer\GAL421-7 causes class IV dendritic arborizing neuron dendrite patterning defects.
