Targeted transgenesis reveals discrete attenuator functions of GRK and PKA in airway beta2-adrenergic receptor physiologic signaling.


Phosphorylation by protein kinase A (PKA) and G protein-coupled receptor kinases (GRKs) desensitize beta2-adrenergic receptor (beta2AR) signaling, and these are thought to be mechanisms involved with cell and organ homeostasis and tolerance to agonists. However, there is little direct evidence that these events are relevant to beta2AR physiological function… (More)
