UASp regulatory sequences drive expression of RhoGAP19D isoform D tagged at the N-terminal end with EGFP. The cDNA used to generate this construct contains sequence changes relative to the reference genome sequence (substitutions Q160H, S278T, T474S, T1509S and T2128S, deletion QQ265--, and insertions --371QQ, ---534QQ and -----572QQQQQ).
