UASt regulatory sequences drive expression of the Gfrl A isoform, which is tagged after the N-terminal signal sequence (after amino acid residue Q31) with Tag:V5.
Scer\GAL4da.G32/GfrlUAS.A.Tag:V5 rescues Gfrldel
Expression of GfrlScer\UAS.A.T:SV5\V5 under the control of Scer\GAL4da.G32 rescues the morphology defect of eggs laid by homozygous Gfrldel females.
