WebNorepinephrine, similar to other catecholamines, is generated from the amino acid tyrosine.Norepinephrine exerts its effects by binding to α- and β-adrenergic receptors (or adrenoceptors, so named for their reaction to the adrenal hormones) in different tissues. In the blood vessels, it triggers vasoconstriction (narrowing of blood vessels), which … WebBinding of norepinephrine or epinephrine causes small changes in the structure of this receptor, which permits the G-protein to bind. This, in turn, causes larger changes in the shape of the α subunit of the G-protein, the first step in a series of reactions that allow the G-protein to regulate intracellular signaling cascades.
