title: Regulation of neuronal adenylate cyclase.
abstract: It appears that several components function in a spirit of integrated cooperation toward the intracellular regulation of neurotransmitter responsiveness. We have demonstrated that cytoskeletal proteins might interact with GNs and that GNs and GNi might interact with one another. At this juncture, it appears that both of these phenomena might occur only in cells of neural origin. Calmodulin and antidepressants may also affect adenylate cyclase in nervous tissue alone. The effects of AAGTP are different in nervous tissue from other tissues, and experiments with that nucleotide have led to the discovery of a new, 32 kDa GTP-binding protein which appears only in neural crest cells. Appreciation of the intricacies of signal transduction through the adenylate cyclase system are developing along with our understanding of that system. When combined with the complexity of neurotransmitter responsiveness, comprehension of the combined systems remains in its infancy, destined to grow as well as to surprise and delight all who are interested.
