UASt regulatory sequences drive expression of an inverted repeat.
The expression of Pak3KK111386 under the control of Scer\GAL4ppk.PG results in a reduced dendritic arborization in third instar larval class IV abdominal dorsal multidendritic ddaC neurons, as compared to controls; expression under the control of Scer\GAL4221 has no obvious effect in third instar larval class I abdominal dorsal multidendritic ddaD and ddaE neurons, as compared to controls.
