Molecular mechanisms of beta-adrenergic receptor desensitization.

TL;DR: Several protein kinases seem to be capable of promoting phosphorylation of the receptors including the cAMP-dependent kinase and protein kinase C, and heterologous desensitization seems to be associated with functional modifications at the level of nucleotide regulatory proteins (Ns and Ni).
Journal Article

Desensitization of beta-adrenergic stimulated adenylate cyclase in turkey erythrocytes.

TL;DR: The data are consistent with the hypothesis that there is a lesion distal to the beta-adrenergic receptor, possibly involving the nucleotide site or the catalytic subunit of adenylate cyclase, causing the desensitization in the isoproterenol treated cells.
Journal Article

(3H)-Propranolol binding sites in myocardial membranes: nonidentity with beta adrenergic receptors.

TL;DR: It is concluded that the [3H]propranolol binding sites studied here are unrelated to the myocardial beta adrenergic receptors and may be involved in mediating the more general membrane or local anesthetic effects of proPRanolol.
Journal ArticleDOI

Dephosphorylation of the beta 2-adrenergic receptor and rhodopsin by latent phosphatase 2.

TL;DR: Study of the ability of four highly purified well characterized protein phosphatases to dephosphorylate preparations of rhodopsin or beta 2-adrenergic receptor which had been highly phosphorylated by beta-adenergic receptor kinase suggests a potential role for the latent phosphatase 2 as a specific receptor phosphat enzyme.
