WebThe rhodopsin protein is attached (bound) to a molecule called 11-cis retinal, which is a form of vitamin A. When light hits this molecule, it activates rhodopsin and sets off a series of chemical reactions that create electrical signals. These signals are transmitted to the brain, where they are interpreted as vision. Web17 aug. 2015 · Approaches that have shown promise include use of gene therapy with microbial opsins such as Chlamydomonas channelopsin to introduce light-regulated ion channels to inner retinal cells 3, 4, 5; gene therapy to introduce the non-visual pigment melanopsin to the inner retina [6]; one-component and two-component optochemical …
