UASt regulatory sequences drive expression of an inverted repeat.
The expression of CCT3KK108238 under the control of either Scer\GAL4tin.CΔ4 or Scer\GAL4HCH.Hand leads to a severe decrease in lifespan and leads to a severe decrease in lifespan and leads to a severe decrease in lifespan and leads to near or fully penetrant cardiac defects, respectively, namely morphological defects, non-beating heart segments and non-beating hearts, as compared to controls. Expression under the control of Scer\GAL4tin.CΔ4 also leads to progressive cardiac dysfunction, as shown by significant increases in heart period, arrhythmia, and diastolic and systolic intervals, and by significant decreases in fractional shortening, and diastolic and systolic diameter, as compared to controls.
