Flies expressing RhoBTB^Scer\UAS.cSa under the control of Scer\GAL4^elav.PU are bang sensitive and remain paralyzed or with spasms for a prolonged period of time after vortexing, whereas control flies recover immediately or within a few seconds, they also display reduced climbing ability - a phenotype also observed with Scer\GAL4^Toll-6-D42, Scer\GAL4^RapGAP1-OK6, Scer\GAL4^repo or Scer\GAL4^DJ757-driven expression of RhoBTB^Scer\UAS.cSa (but the effect with the latter three is weaker).

Expression controlled by either Scer\GAL4^elav.PU or Scer\GAL4^Mef2.247 does not significantly impair either learning or short- or long-term memory tested in a courtship conditioning paradigm.

Expression of RhoBTB^Scer\UAS.cSa driven by Scer\GAL4^RapGAP1-OK6, Scer\GAL4^Toll-6-D42 or Scer\GAL4^elav.PU does not induce any significant alterations in the morphology of neuromuscular junctions in third instar larvae and expression under the combined control of Scer\GAL4⁴⁷⁷ and Scer\GAL4^ppk.PG does not the formation of the dendritic arbor (number and length of dendritic branches) in larval class IV dendritic arborizing neurons
