Rhodopsin, the light sensor of the mammalian visual system, is embedded in the disc membranes of photoreceptor cells. The image above shows an electrospray mass spectrometer, in a darkened, red-lit ...

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 ...

Researchers from the Moscow Institute of Physics and Technology, working with Spanish, French and German colleagues, have determined and analyzed the high-resolution structure of a protein from the ...

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 ...

Researchers have revealed the impact of native lipids on rhodopsin signaling and regeneration, which may usher in a new paradigm for discovery of drugs that target G protein-coupled receptors (GPCRs).

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., ...

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 ...

Any living organism that directly harnesses the sun's energy uses one of three types of energy-converting pigments: chlorophyll, which gives plants their green color, bacteriochlorophyll, or retinal ...

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 ...
