UASt regulatory sequences drive expression of a Sur-8 cDNA. The coding sequence is tagged at the C-terminal end with Tag:FLAG.
abnormal circadian rhythm | adult stage, with Scer\GAL4tim.PU
The expression of Sur-8UAS.Tag:FLAG under the control of one or two copies of Scer\GAL4tim.PU induces longer circadian periods and longer circadian periods with weaker rhythmicity, respectively.
