UAS regulatory sequences drive expression of a short inverted repeat.
Presynaptic expression of gigGL00321 under the control of Scer\GAL4elav.PLu (co-expressed with Dcr-2Scer\UAS.cDa) results in synaptic overgrowth in the neuromuscular junctions of third instar larvae compared to controls. Synaptic overgrowth is also seen when gigGL00321 is expressed postsynaptically under the control of Scer\GAL4G7.
