UASt regulatory sequences drive expression of an inverted repeat.
Adults expressing Ets98BGD4451 under the control of the cardioblast-specific Scer\GAL4tin.CΔ4 driver show significantly reduced survival on day 6 after a shift to 29[o]C compared to control flies.
Expression under the control of Scer\GAL4pnr-MD237 may result in lethality, depending on the insertion line used.
