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 ...

PagePeek introduces an AI-powered paper evaluation system for rhodopsin research, integrating structural, spectroscopic, and ...

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. Emeritus Professor Fumio Hayashi of Kobe University and his colleagues ...

HOUSTON - (July 25, 2016) -- The study of rhodopsin -- the molecule that allows the eye to detect dim light -- has a long and well-recognized history of more than 100 years. Nevertheless, there is ...

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 ...

A general procedure to incorporate membrane proteins in a native state into large single bilayer vesicles is described. The results obtained with rhodopsin from vertebrate and invertebrate retinas are ...

This image shows the structure of rhodopsin embedded in a membrane. The red structure in the middle is the retinal chromophore responsible for absorbing visible light. (Image credit: Kiser et al., ...

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 ...

Light is a powerful source of energy that is used for various biological purposes. Some organisms harness light to produce ATP, the energy currency of cells, while others use light to interpret their ...

Rhodopsin, on the other hand, has one subunit, thus making it difficult to distinguish rhodopsin monomers from rhodopsin dimers, in vivo. To determine whether rhodopsin forms monomers or dimers in ...
