UASt regulatory sequences drive expression of an inverted repeat.
Larvae expressing cmpyKK104023 under the control of Scer\GAL4D42 display a 47% increase in the number of boutons at neuromuscular junction (NMJ) 6/7 and a 49% increase in type I boutons at NMJ 4. Scer\GAL4elav.PU-mediated expression of cmpyKK104023 has a comparable effect.
