UASp regulatory sequences are fused upstream of a cDNA fragment that encodes osk (encodes both protein isoforms and includes the 3'UTR).
Scer\GAL4VP16.otu, Scer\GAL4VP16.nanos.UTR, oskΔi.123.UASp rescues oskA87/Df(3R)p-XT103
Expression of the intronless oskΔi.123.Scer\UAS.P\T, under the control of both Scer\GAL4otu.T:Hsim\VP16 and Scer\GAL4nos.UTR.T:Hsim\VP16, rescues the early oogenesis arrest of oskA87/Df(3R)p-XT103 females.
