Dynamics in rhodopsin

Research output: Contribution to journalShort surveypeer-review

Dancing in the dark: Much is known about the structure and light-induced conformational changes of the mammalian dimlight receptor rhodopsin, a model system for the entire G-protein-coupled receptor family. Less attention has been paid to the dynamic properties of rhodopsin. Growing evidence for the presence of large backbone motions in the inactive dark-state conformation of rhodopsin and their importance for the functional, light-induced conformational changes necessary for signal transduction are reviewed here. Cysteine mutagenesis experiments and spectroscopic techniques are combined to reveal more information about the protein dynamics.
