Background: Norepinephrine is implicated in a wide range of physiological processes through activation of nine different G-protein-coupled receptors (α1a, α1b, α1d, α2a, α2b, α2c, ß1, ß2, ß3). The human ß1-adrenergic receptor is a 477–amino acid protein found in various heart and brain tissues. ß1 has an important role in the contractile action of valves in cardiac and digestive systems.
Application: Functional assays
