UASt regulatory sequences drive expression of an inverted repeat.
CarT knock-down via expression of CarTKK104029 using Scer\GAL4GMR.PF, Scer\GAL4GMR.long or Scer\GAL4oc.1.6 (but not Scer\GAL4repo) causes severe reductions in ON and OFF transients in photoreceptors, indicating disrupted visual signal transduction.
