Rhodopsin: The Basics! - University of Pennsylvania
Rhodopsin, also known as visual purple, is a protein encoded by the RHO gene and a G-protein-coupled receptor (GPCR). It is the opsin of the rod cells in the retina and a light-sensitive receptor protein that triggers visual phototransduction in rods. Rhodopsin mediates dim light vision and thus is … Meer weergeven Rhodopsin was discovered by Franz Christian Boll in 1876. The name rhodospsin derives from Ancient Greek ῥόδον (rhódon) for "rose", due to its pinkish color, and ὄψις (ópsis) for "sight". It was coined in … Meer weergeven 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 therefore reddish-purple, hence the … Meer weergeven Rhodopsin is an essential G-protein coupled receptor in phototransduction. Activation In rhodopsin, the aldehyde group of retinal is covalently linked to the amino group of a lysine residue on the protein in a protonated Meer weergeven • Humphries P, Kenna P, Farrar GJ (May 1992).
