The org-1 N, bi T and bi C domains have been fused in order separated by two or three junctional amino acids (A,G or T). Tag:MYC tags are at the C and N termini. A Tag:HA tag has been placed at the N terminus, a Tag:MYC tag at the C terminus. Expression of this construct is driven by UASt sequences.
When bi::org-1org-1N+biT+biC.Scer\UAS.T:Ivir\HA1,T:Hsap\MYC is driven by Scer\GAL4dpp.blk1 eye development is suppressed. Animals also lack aristae. When bi::org-1org-1N+biT+biC.Scer\UAS.T:Ivir\HA1,T:Hsap\MYC is driven by Scer\GAL4GMR.PF interommatidial bristle development is impaired, but ommatidia look almost normal.
