Figure Legend Snippet: Mutation of palmitoylation site does not inhibit agonist-induced β 2 AR trafficking. A) β 1 β 2 AR-KO cardiomyocytes expressing wild type or mutant flag-β 2 ARs were stimulated with 10 µM isoproterenol to examine receptor internalization or followed by agonist removal to examine receptor recycling. Receptors were stained by anti-flag antibody M1 and Alex 488-conjugated goat-anti-mouse secondary antibody. Maximal internalization of different flag-β 2 ARs in β 1 β 2 AR-KO cardiomyocytes at 30 minute of stimulation was plotted in bar graph. Receptors remaining on the cell surface after internalization (B and D) or recycling (C) were quantified using Alex 488-conjugated flag antibody labeling. Quantitative measurements of cell surface receptor were average from at least three different experiments. *, p
