UASt regulatory sequences drive expression of an inverted repeat.
Scer\GAL4btl.PU barkGD12777 embryos show excessively elongated tracheal tubes.
The formation and correct geometry of tricellular junctions is defective in Scer\GAL4en.PU barkGD12777 wing discs.
Adults expressing barkGD12777 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.
