Rhodopsin was discovered by Franz Christian Boll in 1876. The name rhodopsin derives from Ancient Greek ῥόδον (rhódon) for "rose", due to its pinkish color, and ὄψις (ópsis) for "sight". It was coined in 1878 by the Germa… See more

Rhodopsin is a protein found in the outer segment discs of rod cells. It mediates scotopic vision, which is monochromatic vision in dim light. Rhodopsin most strongly absorbs green-blue light (~500 nm) and appears th… See more

Rhodopsin, like other opsins, is a G-protein-coupled receptor (GPCR). GPCRs are chemoreceptors that embed in the lipid bilayer of the cell membranes and have seven transmembrane domains forming a binding poc… See more

Rhodopsin is an essential G-protein coupled receptor in phototransduction.
In rhodopsin, the aldehyde group of retinal is covalently linked to the amino group of a lysine residue on the protein in a protonated … See more

Mutations in the rhodopsin gene contribute majorly to various diseases of the retina such as retinitis pigmentosa. In general, the defect rhodopsin aggregates with ubiquitin in inclusion bodies, disrupts the intermediate filament net… See more
