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).

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 ...

A team of biophysicists from Russia, Germany, and France, featuring researchers from the Moscow Institute of Physics and Technology, has discovered and studied the structure of the KR2 rhodopsin under ...

The Chesapeake Bay is known for its blue crabs, but those crustaceans are far outnumbered by much tinier residents: bacteria. Every milliliter of bay water is home to thousands to millions of these ...

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 ...
