Noun

beta receptor - receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasodilation and increased heart beat)

beta-adrenergic receptor, beta-adrenoceptor

sympathetic nervous system - originates in the thoracic regions of the spinal cord; opposes physiological effects of the parasympathetic: reduces digestive secretions; speeds the heart; contracts blood vessels

receptor - a cellular structure that is postulated to exist in order to mediate between a chemical agent that acts on nervous tissue and the physiological response

The three-dimensional structure of Super-2, together with computer simulations from the laboratory of associate professor of chemistry Vijay Pande, PhD, suggested this was because the mutant form of IL-2 was less "floppy" than the natural form, so that it presented a "tighter" binding surface to the beta receptor.
