Abstract
G protein–coupled receptors (GPCRs) constitute the largest family of signaling proteins in mammals, mediating responses to hormones, neurotransmitters, and senses of sight, smell and taste. Mechanistic insight into GPCR signal transduction is limited by a paucity of high-resolution structural information. We describe the generation of a monoclonal antibody that recognizes the third intracellular loop (IL3) of the native human β2 adrenergic (β2AR) receptor; this antibody was critical for acquiring diffraction-quality crystals.

P.W.D. characterized antibody binding to the β2AR on HEK-293 cells and spotted on nitrocellulose. S.G.F.R. purified antibody 5, prepared Fab 5, determined the receptor binding surface of Fab 5 by tryptic digestion, determined ligand binding affinities for the β2AR in the presence of Fab 5 and crystallized the β2AR-TMR-Fab 5 complex. C.P. and J.J.F. characterized antibody-induced fluorescence changes of β2AR-TMR. A.M. and D.K.R. generated the antibodies and performed initial antibody screening. T.S.K. prepared monoclonal antibody 5. X.-J.Y. performed bimane fluorescence experiments. H.-J.C. and W.I.W. performed isothermal titration calorimetry experiments on β2AR and Fab 5. P.W.D. and B.K.K. prepared the manuscript.
