Coexpression of bskScer\UAS.cBa with Traf1EP578, under the control of Scer\GAL4GMR.PF, leads to an increase in the disturbance of the ommatidial array in the compound eye in comparison to the eye phenotype resulting from one copy overexpression of Traf1EP578. When hepScer\UAS.cBa is coexpressed with one copy of Traf1EP578, driven by Scer\GAL4GMR.PF, the number of ommatidia and the size of the compound eye are reduced to similar levels seen when two copies of Traf1EP578 are expressed. Expression of Traf1EP578, under the control of Scer\GAL4GMR.PF, in a hep1/Y background, results in the recovery of an eye of wild-type appearance. The number of apoptotic cells in eye dsics of this genotype are decreased compared to Scer\GAL4GMR.PF>Traf1EP578 discs.
Coexpression of Tak1Scer\UAS.cTa, with Traf1EP578, under the control of Scer\GAL4GMR.PF, an increased eye roughness and reduced eye size compared to expression of just Traf1EP578. Scer\GAL4GMR.PF>Traf1EP578 expression in a Tak11 background block the rough-eye phenotype caused by Traf1EP578 overexpression.
