Determinants Present in the Receptor Carboxy Tail Are Responsible for Differences in Subtype-Specific Coupling of β-Adrenergic Receptors to Phosphoinositide 3-Kinase
An agonist-occupied β2-adrenergic receptor (β2-AR) recruits G protein receptor kinase-2 (GRK2) which is recruited to the membrane. Thus, the physical proximity of activated β2-AR and PI-3K allows the activation of the latter. In contrast, it has been observed that the β1-AR is unable to activate the...
