Significats de visual pigments en anglès

Vision relies on photoactivation of visual pigments in rod and cone photoreceptor cells of the retina.

For example, rod and cone visual pigments couple to distinct variants of the heterotrimeric G protein transducin.

Vertebrate rod and cone photoreceptors require continuous supply of chromophore for regenerating their visual pigments after photoactivation.

There are exceptions, the firefly squid Watasenia scintillans possesses three kinds of visual pigments in the eye.

Although nocturnal and diurnal geckos have rod- and cone-based retinas, respectively, they have phylogenetically closely related visual pigments.

Together, these findings clearly show that human visual perception of near infrared light occurs by two-photon isomerization of visual pigments.

The signaling properties of the visual pigments modulate many aspects of the function of rods and cones, producing their unique physiological properties.

Phototransduction is carried out by a signaling pathway that links photoactivation of visual pigments in retinal photoreceptor cells to a change in their membrane potential.

RPE65 is a retinal pigment epithelial protein essential for the regeneration of 11-cis-retinal, the chromophore of cone and rod visual pigments.
