The function of absorbing and responding to incidental electromagnetic radiation, particularly visible light. The response may involve a change in conformation. A receptor that binds an extracellular ligand and transmits the signal to a heterotrimeric G-protein complex. These receptors are characteristically seven-transmembrane receptors and are made up of hetero- or homodimers. Combining with an extracellular or intracellular messenger to initiate a change in cell activity. A G-protein coupled receptor that responds to incidental electromagnetic radiation, particularly visible light. Combining with an extracellular or intracellular messenger to initiate a change in cell activity, and spanning to the membrane of either the cell or an organelle.
