G-Protein-Coupled Receptors - Principles of ... These receptors are coupled to intracellular GTP-binding proteins (G-proteins). Once activated, G-proteins trigger the production of a variety of second messengers (e.g. cyclic AMP [cAMP], inositol triphosphate [IP3], diacylglycerol [DAG], etc.) helping to regulate a number of body functions ranging from sensation to growth to hormone release.

Types of Receptors - Principles of Biology Once the G-protein binds to the receptor, the G-protein changes shape, becomes active, and splits into two different subunits. One or both of these subunits may be able to activate other proteins as a result.
