UAS regulatory sequences drive expression of an inverted repeat.
The expression of Sf3b1HM05176 under the control of Scer\GAL4insc-Mz1407 is embryonic lethal; expression for 2.5 days during the larval stage (temporally regulated by Gal80[ts]) leads to a decrease in the number of type II neuroblast lineage cells. Expression under the control of Scer\GAL4ase.neuro leads to a severe decrease in the number of the type I neuroblast lineage cells.
