Protein Domain : IPR000239

Type:  Family Name:  GPCR kinase
Description:  Rapid regulation of G-protein-coupled receptors (GPCRs) involves agonist-promoted receptor phosphorylation by GPCR kinases (GRKs) []. This processis followed by arrestin binding and transient receptor internalisation. It has been shown that beta-adrenergic receptor kinase (beta ARK-1 or GRK2)follows a similar pattern of internalisation upon agonist activation ofbeta(2)-adrenergic receptors (beta(2)AR) and that beta ARK expressionlevels modulate receptor sequestration []. Such studies indicate afunctional relationship between receptor phosphorylation and sequestration,showing that beta ARK not only translocates from the cytoplasm to theplasma membrane in response to receptor occupancy, but also sharesendocytic mechanisms with the beta(2)AR []. These results suggest a rolefor beta ARK in the sequestration process, or involvement of receptorinternalisation in the intracellular trafficking of the kinase []. Short Name:  GPCR_kinase
