We further show that the interaction of pVHL with beta(2)AR is dependent on proline hydroxylation (proline-382 and -395) and that the dioxygenase EGLN3 interacts directly with the beta(2)AR to serve as an endogenous beta(2)AR prolyl hydroxylase. Under hypoxic conditions, receptor hydroxylation and subsequent ubiquitylation decrease dramatically, thus attenuating receptor degradation and down-regulation.

We investigate the role of the beta 2-adrenergic receptor phosphorylation by protein kinase C in this regulatory process. Mutation of the serine-261, -262, -344 and -345 of the beta 2-adrenergic receptor prevented the phorbol-ester-induced phosphorylation of the receptor. This mutation also abolished the phorbol-ester-induced decrease in high-affinity agonist binding and potency of the beta 2-adrenergic receptor. We suggest that protein kinase C mediated phosphorylation of the receptor promotes its functional uncoupling.

Denopamine is the most selective ligand for β1-receptors, with regard to intrinsic activity and efficacy, and clenbuterol, procaterol, zinterol, AZ 40140d and salbutamol are more selective for the β2-adrenoceptor than the β1-adrenoceptor based on intrinsic activity and efficacy.

pmid sentence
The protein, termed beta-arrestin, was expressed and partially purified. It inhibited the signaling function of beta ARK-phosphorylated beta-adrenergic receptors by more than 75 percent, but not that of rhodopsin. It is proposed that beta-arrestin in concert with beta ARK effects homologous desensitization of beta-adrenergic receptors
