In Drosophila, R7 and R8 photoreceptors, which detect different wavelengths, form synapses in distinct medulla layers. The authors report that Golden Goal and Flamingo, two cell-surface proteins involved in photoreceptor targeting, functionally interact in R8 cells and that their interaction specifies synaptic-layer selection of photoreceptors.
