External Ids for ADRBK1 Gene
The product of this gene phosphorylates the beta-2-adrenergic receptor and appears to mediate agonist-specific desensitization observed at high agonist concentrations. This protein is an ubiquitous cytosolic enzyme that specifically phosphorylates the activated form of the beta-adrenergic and related G-protein-coupled receptors. Abnormal coupling of beta-adrenergic receptor to G protein is involved in the pathogenesis of the failing heart. [provided by RefSeq, Jul 2008]
GeneCards Summary for ADRBK1 Gene
ADRBK1 (Adrenergic, Beta, Receptor Kinase 1) is a Protein Coding gene. Among its related pathways are Signaling by FGFR and Signaling by FGFR. GO annotations related to this gene include phospholipid binding and G-protein coupled receptor kinase activity. An important paralog of this gene is AKT1.
UniProtKB/Swiss-Prot for ADRBK1 Gene
Specifically phosphorylates the agonist-occupied form of the beta-adrenergic and closely related receptors, probably inducing a desensitization of them. Key regulator of LPAR1 signaling. Competes with RALA for binding to LPAR1 thus affecting the signaling properties of the receptor. Desensitizes LPAR1 and LPAR2 in a phosphorylation-independent manner.
Beta-adrenergic receptor kinase 1 (ADRBK1, also known as GRK2) phosphorylates the activated form of the beta adrenergic receptor, thus acting as a form of negative feedback.
