Gene Summary
- Human (157): The beta-adrenergic receptor kinase specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Overall, the beta adrenergic receptor kinase 2 has 85% amino acid similarity with beta adrenergic receptor kinase 1, with the protein kinase catalytic domain having 95% similarity. These data suggest the existence of a family of receptor kinases which may serve broadly to regulate receptor function. [provided by RefSeq]
- Rat (25372): catalzyes phosphorylation of the beta-adrenergic receptor; may mediate desensitizaton of synaptic receptors; may regulate bone formation [RGD]
