Relief of opsin desensitization and prolonged excitation of rod photoreceptors by 9-desmethylretinal.
The 9-methyl group of 11-cis-retinal plays a crucial role in photoexcitation of the visual pigment rhodopsin. A hydrogen-substituted analogue, 11-cis-9-desmethylretinal, combines with opsin to form a pigment that produces abnormal photoproducts and diminished activation of the GTP-binding protein tr...
