UAS regulatory sequences drive expression of a short inverted repeat.
Expression of SMC2HMS00360 under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 results in dramatic loss of germline stem cells (GMC) in the adult testes, whereas expression under Scer\GAL4C587 leads to GMC differentiation defects and Scer\GAL4bam.T:Hsim\VP16-driven expression has no obvious effect on the cells.
