G protein coupled receptor kinases (GRK) phosphorylate and thereby desensitize G protein coupled receptors (GPCR) including β-adrenergic receptors (βAR), which are critical regulators of cardiac function. We identified the Raf kinase inhibitor protein (RKIP) as an endogenous inhibitor of GRK2 that leads to increased cardiac contractility via βAR activation. RKIP binds to the N-terminus (aa1-185) of GRK2, which is important for the GRK2/receptor interaction. Thereby it interferes with the GRK2/receptor interaction without interference with cytosolic GRK2 target activation. In this project, the RKIP/GRK interface was investigated to develop strategies that simulate the effects of RKIP on βAR. RKIP binding to different isoforms of GRK expres...
