UASt regulatory sequences drive expression of an inverted repeat.
The expression of promLGD2271 under the control of Scer\GAL4hh-Gal4 induces a small wing disc pouch, fewer extracellular vesicles and absent or severely shortened/misshapen in microvilli in the wing disc posterior compartment;. The wing is also small.
Adults expressing promLGD2271 under the control of Scer\GAL4Ilp2.PR survive longer under starvation conditions than controls.
Adults expressing prominin-likeGD2271 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.
