<scene name='77/778331/Rhodopsin_and_ligand/1'>Rhodopsin and Ligand</scene> This is rhodopsin with 11-cis retinal bound. After 11-cis retinal becomes activated and becomes all-trans, rhodopsin undergoes the conformational change to become metarhodopsin I and then metarhodopsin II which is the fully active form of rhodopsin. Metarhodopsin II then associates with the G protein transducin and the signal cascade can continue. | <scene name='77/778331/Rhodopsin_and_ligand/1'>Rhodopsin and Ligand</scene> This is rhodopsin with 11-cis retinal bound.
