UASt regulatory sequences drive expression of an inverted repeat.
increased cell number | spermatogenesis, with Scer\GAL4tj.PU
lethal, with Scer\GAL4pnr-MD237
lethal, with Scer\GAL4tin.CΔ4
lethal - all die during larval stage, with Scer\GAL4Mef2.PR
cyst progenitor cell | ectopic, with Scer\GAL4tj.PU
Expression under the control of Scer\GAL4Mef2.PR results in late larval lethality.
Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage.
