Rhodopsin - Wikipedia
Rhodopsin, also known as visual purple, is a protein encoded by the RHO gene and a G-protein-coupled receptor (GPCR). It is a light-sensitive receptor protein that triggers visual phototransduction in rods. Rhodopsin mediates dim light vision and thus is extremely sensitive to light. When rhodopsin is exposed to … See more
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 German … See more
