UASt regulatory sequences drive expression of an inverted repeat.
Expression of mRpS33KK109357 in the heart under the control of Scer\GAL4tin.CΔ4 results in severely abnormal heart function (decreased fractional shortening) without causing significant lethality.
When mRpS33KK109357 is expressed in the heart under the control of Scer\GAL4tin.CΔ4 and restricted to adult stages using Scer\GAL80ts.αTub84B results in abnormal heart size and reduced cardiac function compared to controls.
