UAS regulatory sequences drive expression of a short inverted repeat.
Expression of brnHMC04074 under the control of Scer\GAL4nSyb.PS or Scer\GAL4RapGAP1-OK6, but not Scer\GAL4C57 or Scer\GAL4repo, significantly increases bouton number and satellite bouton number at the neuromuscular junction of muscle 4, compared to controls; in the case of Scer\GAL4nSyb.PS, but not Scer\GAL4RapGAP1-OK6, bouton size is also significantly reduced, compared to controls.
