UASt regulatory sequences drive expression of an inverted repeat.
Flies expressing CG4721GD6237 under the control of Scer\GAL4dan-AC116 have small, misshapen eyes. There is a patch of 10-20 relatively normal ommatidia at the posterior of the eye (near the point at which the morphogenetic furrow initiates in the eye disc), with a highly distorted retinal structure anteriorly.
Adults expressing CG4721GD6237 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.
