UASt regulatory sequences drive expression of the coding region of brat, tagged with EGFP at the N-terminus.
larval RP2 motor neuron | increased number, with Scer\GAL4VP16.mat.αTub67C
Expression of bratScer\UAS.T:Avic\GFP-EGFP, under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16, results in embryos with three (29.7% of cases) or four (7.1% of cases) RP2 neurons per segment instead of the wild-type number of two per segment.
