Recent advances in structure, binding sites with ligands and pharmacological function of β-adrenoceptors obtained by molecular biology and molecular modeling

The structure, binding sites interacting with ligands and the physiological functions of G-protein coupled beta-adrenoceptors (beta-ARs) are being elucidated by molecular biology and molecular modeling studies. The definition given amino acid sequences of beta-ARs in molecular biology and the analysis of three-dimensional and functional binding sites interacting with ligands by molecular modeling may be important for identifying other functional beta-ARs in various tissues and discovering new drugs. Thus, this review focuses on the interaction sites for receptor-ligand and roles of functional beta-ARs as studied by molecular biology and molecular modeling.
