Figure 4From: GRK2 blockade with βARKct is essential for cardiac β2-adrenergic receptor signaling towards increased contractilitySchematic illustration of the signaling pathways discussed in the present study that are elicited by β 2 AR activation in cardiac myocytes and are affected by GRK2 inhibition with βARKct. CA: Catecholamine; AC: Adenylyl cyclase; ATP: adenosine triphosphate. See text for details and all other molecular acronym descriptions.Back to article page
