UASt regulatory sequences drive expression of a synthetic version of Scr consisting of the YPWM motif, the homeodomain and the small C-terminus. The protein contains the mutation E19G. The protein is tagged at the N-terminal end with N-Venus, a non-fluorescent split fluorescent protein fragment. Designed to be used in a bimolecular fluorescence complementation (BiFC) assay to study protein-protein interactions in vivo.
Co-expression of ScrSynth.E19G.Scer\UAS.N.T:Avic\GFP-VN and ScrSynth.E19G.Scer\UAS.N.T:Avic\GFP-VC under the control of Scer\GAL4hs.PB does not result in the formation of ectopic salivary glands in the embryo.
Co-expression of ScrSynth.E19G.Scer\UAS.N.T:Avic\GFP-VN and ScrSynth.E19G.Scer\UAS.N.T:Avic\GFP-VC under the control of Scer\GAL4nullo.PG does not result in the transformation of mesothoracic and metathoracic segments towards prothoracic segments in the embryo.
Construct for BiFC analysis (reconstitution of YFP fluorescence occurs when the T:Avic\GFPVN tag in this construct is brought together in the cell with a protein containing the T:Avic\GFPVC tag).
