The expression of BicD^GD11974 under the control of Scer\GAL4²²¹, in combination with Dicer-2 for efficient RNAi, results in third instar larval class I abdominal dorsal multidendritic ddaD and ddaE neurons exhibiting dendrite branch misrouting, as compared to controls; expression under the control of Scer\GAL4^ppk.PG, in combination with Dicer-2 for efficient RNAi, results in no obvious dendrite morphology defects in class IV abdominal dorsal multidendritic ddaC neurons, as compared to controls.

Expression of BicD^GD11974 under the control of Scer\GAL4^upd results in a reduction in the number of outer border follicle cells compared to wild type and also results in defects in border follicle cell migration.

Adults expressing BicD^GD11974 under the control of Scer\GAL4^elav.PLu (in the presence of Dcr-2^Scer\UAS.cDa to increase the efficiency of RNAi) can show significantly reduced avoidance of noxious temperature (46[o]C) compared to control flies, depending on the particular P{GD11974} insertion line used.

Expression under the control of Scer\GAL4^pnr-MD237 results in loss of bristles on the notum in 0% or 20-30% of the Scer\GAL4^pnr-MD237 expression domain, depending on the insertion line used.

Expression under the control of Scer\GAL4^pnr-MD237 results in planar polarity defects in the orientation of bristles of the notum in 0% or 30-40% of the Scer\GAL4^pnr-MD237 expression domain, depending on the insertion line used.
