UAS regulatory sequences drive expression of a short inverted repeat.
The expression of Ctr9HMS00619 under the control of Scer\GAL4da.PU leads to lethality; expression under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 leads to the progressive loss of germline cells from the germarium, the nuclei of which exhibit severe morphological defects and polyploidy, as compared to controls.
