Data Sheet

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 α1a-adrenoceptor is highly expressed in human vasculature. As with the other α1-ARs, α1a is used by the sympathetic nervous system to regulate systemic arterial blood pressure and blood flow. The α1-ARs also play a major role in cardiac and vascular smooth muscle cells. The knockout mouse models lacking the α1a-adrenergic receptors have highlighted the potential implications of this receptor subtype in variety of functions including the regulation of renal artery contractions, smooth muscle contractions, and vasoconstriction.
