      Reference

      Adults expressing Ube3aC941A.Scer\UAS under the control of Scer\GAL4elav.PU show learning defects (significantly reduced performance in a aversive phototaxis suppression assay compared to controls).

      (Chakraborty et al., 2015)

      Flies expressing Ube3aC941A.Scer\UAS under the control of Scer\GAL4elav.PLu display normal climbing behaviour.

      (Wu et al., 2008)

      Flies expressing Ube3aC941A.Scer\UAS in the eye, under the control of Scer\GAL4GMR.PF display normal adult eyes. Flies expressing Ube3aC941A.Scer\UAS in the wing, under the control of Scer\GAL4Bx-MS1096, display normal adult wings. Flies expressing Ube3aC941A.Scer\UAS ubiquitously, under the control of Scer\GAL4αTub84B.PL, are viable.

      Fails to rescue

      Ube3aC941A.UAS/Scer\GAL4elav.PU fails to rescue Ube3aunspecified

      (Chakraborty et al., 2015)
      Comments

      Expression of Ube3aScer\UAS.cWa under the control of Scer\GAL4elav.PU does not rescue the learning defects (reduced performance in a aversive phototaxis suppression assay) of adults which have a maternally inherited null mutation of Ube3a.
