Rhodopsin is the first G-protein-coupled receptor (GPCR) with its three-dimensional structure solved by X-ray crystallography. The crystal structure of rhodopsin has revealed the molecular mechanism ...

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.

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 ...

Proteins common in multiple species were compared to understand the relationship between how proteins change shape, both over seconds or minutes and throughout evolution. The image shows the ...

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 ...

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 ...

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 ...

Scientists have identified two non-retinoid compounds that may be able to treat retinitis pigmentosa (RP), a group of inherited eye diseases that cause blindness. The compounds were discovered by ...

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 ...
