Three-dimensional structure of bovine rhodopsin. The seven transmembrane domains are shown in varying colors. The retinal chromophore is shown in red.
Vertebrate visual opsins are a subclass of ciliary opsins and mediate vision in vertebrates. They include the opsins in human rod and cone cells. They are often abbreviated to opsin, as they were the first opsins discovered and are still the most widely studied opsins.[1]
