Flies expressing Cul-3ΔC.Scer\UAS under the control of Scer\GAL4tim.PE show altered morning anticipatory activity under light-dark conditions. Under constant darkness conditions, the flies either become arrhythmic for locomotor activity or display weak rhythms.
Expression of gftΔC.Scer\UAS under the control of Scer\GAL4dpp.blk1 or Scer\GAL4sca-4512 has no effect on wing development.
