The light-triggered translocation of trplninaE.T:Avic\GFP-EGFP is partially abolished in inaDttd10 flies. trplninaE.T:Avic\GFP-EGFP is detected at the base of the rhabdomeres and only a small amount is located in the cell body.
Light-raised inaDttd10 in trans with inaDT1 shows partial translocation of trplninaE.T:Avic\GFP-EGFP from the rhabdomere to the cell body. It should be noted that the trplninaE.T:Avic\GFP-EGFP translocation defect in homozygous inaDttd10 mutants is more severe than in trans with inaDT1. inaDttd10/inaDT1 flies exhibit almost normal internalisation in some photoreceptor cells of each ommatidium whereas the internalisation defect is observed in all photoreceptor cells in homozygous inaDttd10 mutants.
