== Function ==
[[http://www.uniprot.org/uniprot/ARBK1_HUMAN ARBK1_HUMAN]] 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.<ref>PMID:19306925</ref>  [[http://www.uniprot.org/uniprot/GBG2_BOVIN GBG2_BOVIN]] Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.

== Publication Abstract from PubMed ==
G protein-coupled receptor kinase 2 (GRK2) is a pharmaceutical target for the treatment of cardiovascular diseases such as congestive heart failure, myocardial infarction, and hypertension. To better understand how nanomolar inhibition and selectivity for GRK2 might be achieved, we have determined crystal structures of human GRK2 in complex with Gbetagamma in the presence and absence of the AGC kinase inhibitor balanol. The selectivity of balanol among human GRKs is assessed.
