The alpha-2 (α2) adrenergic receptor (or adrenoceptor) is a G protein-coupled receptor (GPCR) associated with the G i heterotrimeric G-protein. It consists of three highly homologous subtypes, including α 2A -, α 2B -, and α 2C -adrenergic. Some species other than humans express a fourth α 2D -adrenergic receptor as well. [1]
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) agonists and alpha-2 (α 2) agonists, which are used to treat high blood ...

The alpha-adrenergic receptor has two subclasses α 1 and α 2. Alpha 2 receptors are associated with sympatholytic properties. Alpha-adrenergic agonists have the opposite function of alpha blockers. Alpha adrenoreceptor ligands mimic the action of epinephrine and norepinephrine signaling in the heart, smooth muscle and central nervous system, with
Furthermore, located in the intracellular side close to the membrane is a small alpha helix, often referred to as helix 8 (H8). The crystallographic structure of the adenosine A 2A receptor reveals a ligand binding pocket distinct from that of other structurally determined GPCRs (i.e., the beta-2 adrenergic receptor and rhodopsin).

The adenosine receptors (or P1 receptors[1]) are a class of purinergic G protein-coupled receptors with adenosine as the endogenous ligand. [2] There are four known types of adenosine receptors in humans: A 1, A 2A, A 2B and A 3; each is encoded by a different gene. The adenosine receptors are commonly known for their antagonists caffeine ...
