Noun
retinal protein formed by the action of light on rhodopsin
Source: WordNet"Co-translational targeting and translocation of the amino terminus of opsin across the endoplasmic membrane requires GTP but not ATP". Source: Internet
Rhodopsin is composed of the 11-cis-retinal covalently linked via a Schiff base to the opsin protein (either rod opsin or blue, red or green cone opsins). Source: Internet
This molecule is then transported into the photoreceptor cells of the retina, where it acts as a light-activated molecular switch within opsin proteins that activates a complex cascade called the visual cycle. Source: Internet
When stimulated by light, rhodopsin splits into a protein and a cofactor: opsin and all-trans-retinal (a form of vitamin A). Source: Internet
Within the eye, 11-cis-retinal is bound to the protein " opsin " to form rhodopsin in rods and iodopsin ( cones ) at conserved lysine residues. Source: Internet
