More insight into how vision works
PSI scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the protein is responsible for relaying the optical signal from the eye to the brain. If a genetic disorder disrupts the molecular function in a person, they will go blind. Scientists have deciphered the protein’s three-dimensional structure, preparing the way for innovative medical treatments. The study is published in the scientific journal Nature Structural & Molecular Biology.
