Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate [PDF]
Nature Communications, 2017 It is currently thought that visual pigments in vertebrate photoreceptors are regenerated exclusively through enzymatic cycles. Here the authors show that mammalian photoreceptors also regenerate opsin pigments in light through photoisomerization of N ...

Photoreceptor distributions, visual pigments and the opsin repertoire of Atlantic halibut (Hippoglossus hippoglossus) [PDF]
Scientific Reports, 2022 Fishes often have cone photoreceptors organized in lattice-like mosaic formations. In flatfishes, these lattices undergo dramatic changes during metamorphosis whereby a honeycomb mosaic of single cones in the larva is replaced by a square mosaic of ...

Spontaneous activation of visual pigments in relation to openness/closedness of chromophore-binding pocket [PDF]
eLife, 2017 Visual pigments can be spontaneously activated by internal thermal energy, generating noise that interferes with real-light detection. Recently, we developed a physicochemical theory that successfully predicts the rate of spontaneous activity of ...

Ultrafast Transient Absorption Spectra and Kinetics of Rod and Cone Visual Pigments [PDF]
Molecules, 2023 Rods and cones are the photoreceptor cells containing the visual pigment proteins that initiate visual phototransduction following the absorption of a photon.

Evolution and mechanism of spectral tuning of blue-absorbing visual pigments in butterflies. [PDF]
PLoS ONE, 2010 The eyes of flower-visiting butterflies are often spectrally highly complex with multiple opsin genes generated by gene duplication, providing an interesting system for a comparative study of color vision.

Schiff base deprotonation and structural changes in a mouse UV-sensitive cone visual pigment revealed by FTIR spectroscopy at 77 K [PDF]
Biophysics and PhysicobiologyUV-sensitive cone visual pigments are widespread among vertebrates, including birds, fish, and rodents such as mice, and play essential roles in non-primate vision.

The Role of Pigments in Light Color Variation of the Firefly Photinus pyralis [PDF]
Ecology and EvolutionFirefly light color does not appear to directly influence mate choice, but it seems to be under selection to enhance signal detectability by increasing contrast with the visual background.

Retinoids in the visual cycle: role of the retinal G protein-coupled receptor
Journal of Lipid Research, 2021 Driven by the energy of a photon, the visual pigments in rod and cone photoreceptor cells isomerize 11-cis-retinal to the all-trans configuration.
