title: The beta-adrenergic receptor and its mode of coupling to adenylate cyclase.
abstract: The article first includes a discussion on the classification of catecholamine receptors followed by a discussion on the binding studies of beta-receptors and their affinity labeling. Next a brief discussion on the solubilization and the current attempts to purify the receptor is presented. A large section is then devoted to the mode of coupling between beta-receptors and cyclase where much space is devoted to the role of GTP and of the membrane matrix. The review ends with a discussion on beta-receptor desensitization, supersensitivity, and the "spare receptor" concept.
