Proteins {beta-adrenergic catecholamine receptor} {beta-receptor} {adrenergic catecholamine} can bind catecholamines. Binding couples to G protein and adenylate cyclase metabolism. Beta-receptor protein strongly binds ISO, binds epinephrine, and weakly binds norepinephrine. Binding can cause vasodilation, uterine contraction inhibition, cardiac stimulation, and bronchodilation. If guanosine triphosphate (GTP) is present, beta-receptors have only low-affinity catecholamine binding.
