UASt regulatory sequences drive expression of an inverted repeat.
Expression of shvKK101364 under the control of Scer\GAL4nSyb.PS (but not Scer\GAL4how-24B) leads to a synapse overgrowth phenotype with an increase in the number of synaptic boutons as well as immature, undifferentiated 'ghost boutons' on the neuromuscular junctions in third instar larvae.
