Rhodopsin - Wikipedia
Rhodopsin, also known as visual purple, is a protein encoded by the RHO gene [5] and a G-protein-coupled receptor (GPCR). It is a light -sensitive receptor protein that triggers visual phototransduction in rods.

Rhodopsins at a glance - PubMed
2021年11月15日 · Rhodopsins are photoreceptive membrane proteins consisting of a common heptahelical transmembrane architecture that contains a retinal chromophore. Rhodopsin was first discovered in the animal retina in 1876, but a different type of rhodopsin, bacteriorhodopsin, was reported to be present in the cel ….
Rhodopsin - an overview | ScienceDirect Topics
Rhodopsin is the vertebrate visual protein of rod cells which is responsible for dim light vision. Rhodopsin consists of a protein chain, opsin (Mr ≃ 38,000), to which a molecule of 11-cis retinal is bound.
Microbial and Animal Rhodopsins: Structures, Functions, and …
2013年12月23日 · Rhodopsin differs from diffusible ligand-activated GPCRs by its covalently linked retinal and photochemical core enabling photosensory function. 11-cis-retinal serves together with the constraints described above in highly efficient stabilization of the inactive dark state of rhodopsin.
