UAS regulatory sequences drive expression of the trio GEF1 and GEF2 domains, tagged at the 3' end with 8 copies of the Tag:MYC tag.
photoreceptor cell & axon, with Scer\GAL4GMR.PF
Expression of trioGEF1-GEF2.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4GMR.PF causes moderate defects in photoreceptor axon projection.
