The RMCE cassette in TI{T-GEM.0}EhGal4 has been replaced with sequence encoding Eh third intron sequence (from 3' to the original insertion site) and the coding sequence of Eh exon 4, following by T2A-p65(AD)::Zip+. This results in the reconstitution of full-length Eh coding sequence, and the presence of the T2A sequence allows separate translation of the p65(AD)::Zip+ hemidriver under the control of endogenous Eh regulatory sequences.
