Structure of the C13.18 RNA Aptamer in Complex with G Protein-Coupled Receptor Kinase 2
Structural highlights
FunctionARBK1_BOVIN 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 (By similarity). See Also
