The role of the guanine nucleotide exchange reaction in the regulation of the beta-adrenergic receptor and in the actions of catecholamines and cholera toxin on adenylate cyclase in turkey erythrocyte membranes.


Several changes were noted in the characteristics of the turkey erythrocyte beta-adrenergic receptor and in the kinetic properties of adenylate cyclase following pretreatment of erythrocyte membranes with isoproterenol and GMP, and thorough washing to remove these agents. The changes include modifications in the binding of agonist (isoproterenol) and in… (More)
