When a photon of light is absorbed, 11-cis retinal is transformed to all-trans retinal, and it moves to the exit site of rhodopsin. It will not leave the opsin protein until another fresh chromophore comes to replace it, except for in the ABCR pathway. Whilst still bound to the opsin, all-trans retinal is transformed into all-trans retinol by all-trans Retinol Dehydrogenase. It then proceeds to the cell membrane of the rod, where it is chaperoned to the Retinal Pigment Epithelium (RPE) by Int… WebRosalie K. Crouch, ...

WebThe visual cycle for rods occurs via the RPE (Fig. 5). The visual cycle for cones is less clear. It can be that part of the cone all-trans retinal is recycled by the RPE and part is recycled by Muller glia cells. Figure 5. The visual cycle (adapted from Thompson and Gal (597).

Web17 Nov 2024 · One visual-cycle gene (rbp1) and one cone and rod phototransduction gene (gucy2f) found in the A. bituberculatus genome-wide sequencing were not found in the A. bicolor eye transcriptome, and so are perhaps not being expressed in the Anilios eye. Similarly, gucy2f is found in the genome but not eye transcriptome of Thamnophis sirtalis .
