UASt regulatory sequences drive expression of an inverted repeat.
Expression of wkdGD11617 in the trachea under the control of Scer\GAL4btl.PS results in a terminal cell "U-turn" phenotype, in which seamless tubes execute a series of 180[o] turns.
Adults expressing wkdGD11617 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.
Co-expression of wkdGD11617 alters the location of the ectopic seamless tube phenotype seen in tracheal terminal cells expressing btlScer\UAS.T:λ\cI-DD under the control of Scer\GAL4btl.PS. Instead of being restricted to the soma, extra tubes are either found throughout the cell (in the soma and at the branch tip) or solely at the branch tip.
