Any of a group of receptors on cell membranes that are thought to be associated with vasoconstriction, relaxation of intestinal muscle, and contraction of the nictitating membrane, iris dilator muscle, smooth muscle of the spleen, and muscular layer of the uterine wall. Also called alpha-adrenergic receptor.

It is interesting to note that the ligand binding activity is lost on treatment with most common detergents like Triton X-100 or sodium cholate, but not digitonin, and that [beta] adrenergic receptors as well as rhodopsin and muscarinic receptors were also found to be solubilized in their active forms only with digitonin (14) when these three proteins were not thought to belong to the same family.
