Specifically phosphorylates the agonist-occupied form of the beta-adrenergic and closely related receptors, probably inducing a desensitization of them (PubMed:19715378). Key regulator of LPAR1 signaling (PubMed:19306925). Competes with RALA for binding to LPAR1 thus affecting the signaling properties of the receptor (PubMed:19306925). Desensitizes LPAR1 and LPAR2 in a phosphorylation-independent manner (PubMed:19306925). Positively regulates ciliary smoothened (SMO)-dependent Hedgehog (Hh) signaling pathway by facilitating the trafficking of SMO into the cilium and the stimulation of SMO activity (By similarity). Inhibits relaxation of airway smooth muscle in response to blue light (PubMed:30284927).

The protein GRK2 also known as G protein-coupled receptor kinase 2 is an important enzyme involved in the regulation of G protein-coupled receptors (GPCRs). It has a molecular weight of approximately 80 kilodaltons. GRK2 is widely expressed in many tissues especially in the heart and brain where it plays an important role in cellular signaling processes. Its primary action is phosphorylating activated GPCRs which leads to receptor desensitization and downregulation modulating cellular responses to stimuli.
GRK2 acts by coordinating with other proteins to regulate signal transduction pathways. It usually forms a complex with arrestins which prevent further signaling by blocking G protein coupling and directing receptors towards internalization pathways. This kinase acts to modulate receptor activity and maintain cellular homeostasis. GRK2 is essential for preventing overstimulation of cells playing a role in neurobiology and cardiology.
GRK2 plays an important role in the adrenergic receptor signaling pathways including the beta-adrenergic and alpha-adrenergic pathways. It participates in the regulation of cardiac output and vascular tone by influencing the response of cells to catecholamines like adrenaline and noradrenaline. Proteins related to GRK2 in these pathways include adrenergic receptor subtypes and arrestin proteins. Voltage-gated calcium channels also interact with GRK2 linking it to calcium signaling pathways vital for muscle contraction and neurotransmitter release.
Research highlights GRK2's involvement in heart failure and hypertension. In heart failure elevated levels of GRK2 correlate with worsened cardiac function due to impaired beta-adrenergic receptor signaling. GRK2 is also linked to the development of hypertension through its effects on vascular smooth muscle cells and blood pressure regulation. Its interaction with proteins like arrestins suggests potential therapeutic targets for these cardiovascular conditions. Understanding and modulating GRK2 activity might offer approaches to treat these disorders.
