UASt regulatory sequences drive expression of an inverted repeat.
Down-regulation of scw in Pdf-positive neurons, through expression of scwKK109520 under the control of Scer\GAL4P2.4.Pdf induces mild locomotor arrhythmicity. Expression of scwKK109520 under the control of Scer\GAL4tim.PE and suppressed in Pdf-positive cells through the presence of Scer\GAL80Pdf.PS results in some rescue of the arrhythmic phenotype.
