17012621-1	2007	Dephosphorylation of the cyclic AMP-dependent protein kinase (PKA) site phosphoserine 262 and the G protein-coupled receptor kinase (GRK) site phosphoserines 355 and 356 of the beta2-adrenergic receptor (beta2AR) were characterized in both intact human embryonic kidney 293 cells and subcellular fractions and were correlated with the rate of resensitization of isoproterenol stimulation of adenylyl cyclase after treatment with isoproterenol and blockade by antagonist.	Phosphoserine	143-157	adrenoceptor beta 2	Homo sapiens	177-202	
14722251-0	2004	Characterization of agonist stimulation of cAMP-dependent protein kinase and G protein-coupled receptor kinase phosphorylation of the beta2-adrenergic receptor using phosphoserine-specific antibodies.	Phosphoserine	166-179	adrenoceptor beta 2	Homo sapiens	134-159	
14722251-2	2004	In this study the kinetics of phosphorylation of the third intracellular loop PKA site Ser262 and the putative C-tail GRK sites Ser355, Ser356 of the human beta2AR overexpressed in human embryonic kidney (HEK) 293 cells were characterized using phosphoserine-specific antibodies.	Phosphoserine	245-258	adrenoceptor beta 2	Homo sapiens	156-163
