Adrenoceptors (also called Adrenergic receptors) are the receptors for the catecholamines adrenaline and noradrenaline (called epinephrine and norepinephrine in the United States). Adrenaline and noradrenaline play important roles in the control of blood pressure, myocardial contractile rate and force, airway reactivity, and a variety of metabolic and central nervous system functions.

 

The Adrenoceptors are members of the G-protein-coupled receptor (GPCR) superfamily of membrane proteins. They share a common structure of seven putative transmembrane domains, an extracellular amino terminus, and a cytoplasmic carboxyl terminus.The Adrenoceptors are divided into three types: a₁, a₂ and b adrenoceptors. Each type is further divided into at least three subtypes: a_1A, a_1B, a_1D, a_2A, a_2B, a_2C, b₁, b₂, b₃. ^1,2

They are expressed in nearly all peripheral tissues and in the central nervous system.^1,2

 

All a₁-Adrenoceptors (a₁-ARs) activate phospholipases C and A2.³

In addition to mobilizing intracellular calcium, the a₁-ARs have also been shown to activate calcium influx via voltage-dependent and independent calcium channels.⁴

 

The a_1B- Adrenoceptor shows the highest levels in the spleen, kidney, cerebellum,

and fetal brain.⁵

a_1B- Adrenoceptor causes contraction of smooth muscle cells and thereby controls vascular tone, blood pressure, and accelerates the development of atherosclerosis.⁵

 

Alomone Labs is pleased to offer a highly specific antibody directed against an extracellular epitope of the human a_1B- Adrenoceptor. The Anti- a_1B^- Adrenoceptor (extracellular) (#AAR-018) can be used for Western blotting, Immunocytochemistry and Indirect Flow Cytometry applications. It has been designed to recognize a_1B- Adrenoceptor from human, rat and mouse samples.
