UASp regulatory sequences drive expression of trk containing the amino acid replacement P82A.
Scer\GAL4VP16.nanos.UTR/trkP82A.UASp partially rescues trkΔ
Maternal expression of trkP82A.Scer\UAS.P\T under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 rescues the phenotype of embryos laid by trkΔ females in 9% of cases.
