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 ...

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 ...

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., ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...
