The catecholamines, in particular norepinephrine and epinephrine, are targets of the G protein-coupled receptor class known as adrenergic receptors. These receptors are found on numerous cells, and when a catecholamine binds to one of these receptors, the sympathetic nervous system is typically stimulated. The fight-or-flight response is controlled by the sympathetic nervous system, which causes the eye pupils to dilate, the body to mobilize energy, and the blood supply to skeletal muscle to be diverted from non-essential organs.There are numerous subtypes of the two main groups of adrenergic receptors, and. The receptor subtypes 1 and 2 exist. There are three subtypes of receptors: 1, 2, and 3. They are all associated with Gs proteins, which are associated with adenylate cyclase. Thus, antagonist binding increases the level of the second messenger cAMP inside of the cell. The cAMP-dependent protein kinase (PKA), one of cAMP's downstream effectors, mediates some intracellular processes after hormone binding.
