UASt regulatory sequences drive expression of full-length pins (including 5'UTR sequences but not 3'UTR sequences) which is tagged at the C-terminal end with two copies of the Tag:FLAG tag.
pinsUAS.Tag:FLAG/Scer\GAL4sca.PU rescues pinsP89
Expression of rapsScer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4sca.PU rescues the RP2 neuron duplication seen in rapsP89 embryos.
