In the framework of the 'rotational model', a ligand that binds to the extracellular part of the receptor causes the internal part of the receptor to rotate within the cell membrane, thus essentially regulating the activity inside the cell. In the process, the structural flexibility of the receptors also changes. [Courtesy of Okinawa Institute of Science and Technology, OIST]
