The human β 2 -adrenoceptor is a member of the 7-transmembrane family of receptors, encoded by a gene on chromosome 5, and widely distributed in the respiratory tract. Many drug discovery efforts focus on G protein–coupled receptors (GPCRs), a class of receptors that regulate many physiological processes. An exemplar is the β 2 .2. β -Adrenergic receptors β1-Adrenergic receptors have been located in the heart, the juxtaglomerular cells of the kidney, and the parathyroid gland. β2 -Adrenergic .
The beta 2 adrenergic receptor (beta2AR) is a prototypical Family A GPCR that mediates physiologic responses to adrenaline and noradrenaline.
The human beta (2)-adrenoceptor is a member of the 7-transmembrane family of receptors, encoded by a gene on chromosome 5, and widely distributed in the respiratory tract.Introduction. β agonists constitute the frontline treatment for both asthma and COPD. They exert their bronchodilatory effects via β 2 adrenoceptors (β 2 ARs) located on airway smooth muscle (ASM) cells. Activation of these receptors results in ASM and thus airway relaxation via the molecular processes outlined later in the “Mechanisms of Action” .
The gene encoding the beta 2 -adrenergic receptor ( ADRB2) is one of the most extensively studied genes. It is a small gene consisting of a single exon that encodes a 413-amino acid protein. The beta 2 -adrenergic receptor also is one of the best characterized G-protein-coupled receptors (GRCRs).

The beta2-adrenergic receptor (β2AR) family, which is the largest family of cell surface receptors in humans. Extra attention has been focused on the human GPCRs because they have been studied as important protein targets for pharmaceutical drug development. In fact, approximately 40% of marketed drugs directly work on GPCRs.
The beta adrenergic receptors are single polypeptide chains of 408–477-amino-acid residues. In contrast to the alpha-2 receptors, but similar to the alpha-1 receptors, the beta receptors tend to have longer C-terminal tails (61–97-amino-acid residues) and shorter third intracellular loops (54–80-amino-acid residues).

The β 2-adrenergic receptor (β 2 AR), a prototypic class A GPCR, plays essential roles in cardiovascular and respiratory physiology and is the therapeutic target of clinical drugs such as beta-blockers and beta-agonists ().We previously reported a cell-permeable NAM of the β 2 AR, compound-15 (Cmpd-15), which binds to a cytoplasmic .The human beta (2)-adrenoceptor is a member of the 7-transmembrane family of receptors, encoded by a gene on chromosome 5, and widely distributed in the respiratory tract. Intracellular signaling after beta (2)-adrenoceptor activation is largely affected through cyclic adenosine monophosphate and protein kinase A. Differences in the mechanism .
adrenergic receptor: Any of several sites in the surface membranes of cells innervated by adrenergic neurons. The adrenergic receptors (or adrenoceptors) are a class of metabotropic G protein -coupled receptors that are targets of the catecholamines, especially norepinephrine or noradrenaline, and epinephrine ( adrenaline ). The gene encoding the beta-2 adrenergic receptor is situated on chromosome 5q31 [ 1 ]. It encodes a protein that is a member of the large family of G-protein coupled, seven transmembrane-spanning domain receptors. The receptor is expressed on a variety of cell types in the lung, including airway smooth muscle and .The membrane the receptor is bound to in cells is shown with a gray stripe. The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine .These three classes are alpha 1 (a Gq coupled receptor), alpha 2 (a Gi coupled receptor) and beta (a Gs coupled receptor), and each can be further divided into subtypes . The receptors are located presynaptically in nerves, where they facilitate neurotransmitter release, and in the brain, where they regulate a variety of physiological processes .Iba paBeta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it .
Defective β- adrenergic receptor function is a hallmark of congestive heart failure. Adenylyl cyclase. Adenylyl cyclase is an enzyme that converts ATP to the second-messenger cAMP (3′,5′ cyclic AMP). Congestive heart failure is associated with defective β-adrenergic receptor signaling and decreased AC6 content in LV samples. Similar to other receptors, there are three different ligand types of β 2 AR: agonists, antagonists and inverse agonists. The agonists activate the signaling pathways and increase the receptor’s basal activities. The antagonists block the signaling transductions without affecting the receptor’s basal activities.
Beta-2 adrenoceptors are activated by the catecholamines norepinephrine and epinephrine, and are members of the adrenoceptor family of the 7-transmembrane superfamily of receptors. There are three beta adrenoceptor subtypes: beta-1, beta-2, and beta-3. The beta-2 adrenoceptor is the prototypical G protein-coupled receptor and much is known .Adrenergic receptors are proteins found on the surface of cells that respond to the hormone adrenaline ( epinephrine ). There are three types of adrenergic receptors - alpha, beta, and gamma. Each type responds to a different set of chemical signals from adrenalin. When adrenaline binds to its receptor, it triggers a series of biochemical . The indication for the use of an alpha-receptor modifying medication depends on which receptor is the target: the alpha-1 receptor or the alpha-2 receptor. Further, when administering a pharmacologic agent, it can exert either agonistic or antagonistic activity on the alpha receptors. This activity reviews the various alpha .
