R8-DRA [FBbt_00004209]
R8 photoreceptor of the dorsal rim area of the retina. It expresses the UV-detecting Rhodopsin 3 and extends to medulla layer M6, where it synapses to Dm-DRA2 (Sancer et al., 2019). In expression and morphology it is more similar to R7 cells than other R8 cells (Sancer et al., 2019).
