Bovine Rhodopsin - General Information
Rhodopsin is found in both prokaryotes and eukaryotes. Rhodopsin is a biological pigment that is found in the rods of the retina and is a G-protein-coupled receptor (GPCR). Rhodopsin is very sensitive to light which is why it allows for vision in low-light conditions. However, when rhodopsin is exposed to light it immediately gets bleached and thus, vision will be inhibited. In humans, rhodopsin usually regenerates after about 30 minutes. Rhodopsin of the rods is known for absorbing large amounts of green-blue light and therefore, appears reddish-purple; which is why it is also called "visual purple". Also, Rhodopsin is responsible for monochromatic vision in the dark.After light is absorbed, in order for the rods to continue functioning and for vision to be possible, they must regenerate rhodopsin at a rate that keeps pace with bleaching.
Structure and Function
Rhodopsin consists of two major structural components:
