UASt regulatory sequences drive expression of an inverted repeat.
Expressing reptKK105732 under the control of Scer\GAL4VP16.bam results in immotile sperm.
Testes in individuals expressing reptKK105732 under the control of Scer\GAL4VP16.bam lack motile sperm despite sperm bundles being largely normal, as compared to controls.
Expression of reptKK105732 under the control of any of the following: Scer\GAL4Act5C.PI, Scer\GAL4ey.PH or Scer\GAL4en.PU is completely lethal and largely so when driven by Scer\GAL4nub.PK - only few escapers eclose and those have no wings. Expression controlled by Scer\GAL4GMR.PF has no overt adult phenotype.
