Flies expressing Mmus\PrnpM205S.Scer\UAS under the control of Scer\GAL4da.G32 have similar survival curves to control flies.
Adults expressing Mmus\PrnpM205S.Scer\UAS under the control of Scer\GAL4BG380 show similar climbing ability to control flies.
Expression of Mmus\PrnpM205S.Scer\UAS under the control of Scer\GAL4ey-OK107 does not result in mushroom body defects.
Young adults co-expressing both Mmus\PrnpWT.Scer\UAS and Mmus\PrnpM205S.Scer\UAS under the control of Scer\GAL4ey-OK107 show abnormal development of the dorsal projections of the mushroom body, a phenotype not seen when either Mmus\PrnpWT.Scer\UAS or Mmus\PrnpM205S.Scer\UAS is expressed singly. Further thinning of the dorsal and medial projections is seen in 40 day old flies.
