Activation of G-protein coupled receptors (GPCR) is not yet understood. A recent structure showed most of rhodopsin in the ground (not activated) state of the GPCR, but the cytoplasmic face, which couples to the G protein in signal transduction, was not well-defined. We have determined an experimental three-dimensional structure for rhodopsin in the unactivated state, which shows good agreement with the crystal structure in the transmembrane domain. This new structure defines the cytoplasmic face of rhodopsin. The G-protein binding site can be mapped. The same experimental approach yields a preliminary structure of the cytoplasmic face in the activated (metarhodopsin II) receptor. Differences between the two structures suggest how the receptor is activated to couple with transducin.
