beta adrenergic receptor kinase-1 (ADRBK1, G protein-coupled receptor kinase-2)
Function:
- specifically phosphorylates agonist-occupied form of the beta-adrenergic receptors & closely related receptors, probably inducing a desensitization of them
- interacts with GIT1 (putative)
- interacts with, & phosphorylates chemokine-stimulated CCR5
ATP + [beta-adrenergic receptor]
ADP + [beta-adrenergic receptor] phosphate
Structure:
- belongs to the protein kinase superfamily, AGC Ser/Thr protein kinase family, GPRK subfamily
- contains 1 AGC-kinase C-terminal domain
- contains 1 PH domain
- contains 1 protein kinase domain
- contains 1 RGS domain
Expression: expressed in peripheral blood leukocytes
