A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily.

Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Researchers now revealed that the photoreceptor protein rhodopsin forms ...

IN 1950, Wald, Durell and St. George 1 found a shift of the absorption maximum in a rhodopsin-glycerin mixture illuminated at − 73° C., and they proposed lumi-rhodopsin as the first intermediate in ...

Regeneration of rhodopsin, which completes the rhodopsin cycle described in the following article, occurs spontaneously if the retina of the rat is isolated and sealed in a small chamber.

A new, ultrafast raman spectroscopy method has given researchers a glimpse of the early stages of the vision process. Vision is jump-started by the isomerization of the retinal chromophore in ...

Seeing starts in the rods and cones, two different types of sensory cells in the retina of the eye. The rods are responsible for dark vision and are particularly sensitive to light as a result. A ...

The sense of vision is the most important sense for many animals and humans. The visual pigment rhodopsin is a key protein, it absorbs light which falls onto the visual cells in the retina. There has ...

Forbes contributors publish independent expert analyses and insights. I cover the living world, from microbes to ecosystems. Any living organism that directly harnesses the sun's energy uses one of ...

The P23H mutation within the rhodopsin gene (RHO) causes rhodopsin misfolding, endoplasmic reticulum (ER) stress, and activates the unfolded protein response (UPR), leading to rod photoreceptor ...

In a new study at University of California, Irvine, researchers have revealed the impact of native lipids on rhodopsin signaling and regeneration, which may usher in a new paradigm for discovery of ...

This is a preview. Log in through your library . Abstract Isolated frog retinas were incubated in vitro with a 4-h pulse of [3H]leucine, then chased for 32 h with a nonradioactive amino acid mixture.

A research group including Professors Mitsumasa Koyanagi and Akihisa Terakita of the Osaka Metropolitan University Graduate School of Science has investigated both the genetic information and ...
