UAS regulatory sequences drive expression of a phosphorylation-defective form of Sik3 (carries the amino acid replacement S563A).
abnormal sleep | RU486 conditional, with Scer\GAL4elav.Switch.PO
Expression of Sik3S563A.Scer\UAS under the control of Scer\GAL4elav.Switch.PO (induced by RU-486 treatment) leads to increased daily sleep time of adult flies, as compared to controls.
