Regulation of beta-adrenergic sensitivity by guanine nucleotides in rat brain.
Binding of beta-adrenergic receptor by labelled dihydroalprenolol was inhibited in the presence of GTP or GppNHp in rat brain particulate fractions. The inhibition was suspended when the particulate fraction was pretreated at 30 degrees C for 20 minutes and washed 3 times. It is concluded that the inhibition was due to endogenous bound catecholamines.
