UASt regulatory sequences drive expression of Cul3 carrying a K717R amino acid replacement. The coding sequence is tagged with Tag:FLAG.
abnormal locomotor rhythm, with Scer\GAL4tim.PE
Under constant darkness conditions, flies expressing Cul-3KR.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4tim.PE either become arrhythmic for locomotor activity or display weak rhythms.
