Probing Human Red Cone Opsin Activity with Retinal Analogues. This article is cited by 26 publications. All -trans-retinal is immediately reduced in the photoreceptor to prevent back reactions and to weaken its effectiveness as an agonist before it is transported out of the cell oxidation of 11- cis-retinol occurs in the retinal pigment epithelium and not the rod photoreceptor cell because 11- cis-retinol can act as an agonist and activate the signaling cascade if it were to bind an opsin, effectively adapting the cell to light. Taken as a whole, our study is consistent with the hypothesis that the steps in the visual cycle are optimized such that the rod can serve as a highly sensitive dim light receptor. All -trans-retinal, all -trans-retinol, and 11- cis-retinol are all agonists with all -trans-retinal being the most potent agonist and all -trans-retinol being the least potent. Only 11- cis-retinal acts as an inverse agonist to the opsin. In this study, we have measured the effects of all -trans- and 11- cis-retinals and -retinols on the opsin’s ability to activate transducin to ascertain their potentials for activating the signaling cascade. It is subsequently transported to the retinal pigment epithelium where it is converted to 11- cis-retinol and oxidized to 11- cis-retinal before it is transported back to the photoreceptor to regenerate rhodopsin and complete the visual cycle. All -trans-retinal is then released from the protein and reduced to all -trans-retinol. Upon absorption of a photon, the covalently bound 11- cis-retinal isomerizes to the all- trans form, enabling rhodopsin to activate transducin, its G protein. Rhodopsin is the photosensitive pigment in the rod photoreceptor cell.
