Agonist stimulation increases the turnover rate of beta 2AR-bound palmitate and promotes receptor depalmitoylation.

Abstract excerpt

We have characterized the dynamic nature of beta 2-adrenergic receptor palmitoylation in Sf9 cells. Under basal conditions, the turnover of receptor-bound palmitate is rapid (half-life = 9.8 +/- 1.8 min) compared to the turnover rate of the receptor protein itself (half-life = 109 +/- 10 min). This suggests that an equilibrium between the palmitoylated and nonpalmitoylated forms of the receptor exists at resting...
