LOCALIZATION OF A DROSOPHILA EYE PROTEIN WHICH IS PHOSPHORYLATED AFTER LIGHT STIMULATION

抄録

In fruit fly, Drosophila melanogaster, three eye proteins are known to be phosphorylated by light stimulation (8, 9). Among them, 49 K protein is most abundant. Matsumoto et al. (8, 9) suggested their possible involvement in the visual procasses. In this paper, we describe its cellular localization revealed by immunohistological methods. The protein is localized in all the visual receptor cells including retinular cells (R1-R8) of the adult compound eye, adult ocelli and larval photoreceptor organ. It also exists in their axons. The antigen is shown to be enriched in microvillous rhabdomere and multivesicular cells suggests that it plays an important role in the processes following photoreception and transduction.
