UASt regulatory sequences drive expression of an inverted repeat.
Expression of GaltKK102974 under the control of Scer\GAL4da.G32, Scer\GAL4elav.PU or Scer\GAL4how-24B results in L3 NMJs exhibiting synaptic structural over-elaboration, with a significant increase in synaptic bouton number and synapse branch number; but mean excitatory junction current amplitude is not significantly different in larvae expressing GaltKK102974 under the control of Scer\GAL4da.G32, as compared to controls.
