The beta 3 adrenergic receptor also known as beta-3 adrenoceptor or B3 adrenergic receptor is a member of the adrenergic receptor family that activates the GS protein upon binding ligands like catecholamines. This receptor approximately 408 amino acids in size has a predominant mass of around 45 kDa. It is mainly expressed in adipose tissue but also found in the gallbladder urinary bladder and the gastrointestinal tract. These receptors primarily mediate lipolysis and thermogenesis in brown adipose tissue through interaction with norepinephrine and epinephrine.

Biological function summary

The beta 3 adrenergic receptor plays an important role in energy expenditure and metabolic processes. It does not typically form part of a complex but interacts with GS proteins leading to the activation of adenylyl cyclase and consequent increase in cAMP levels. This receptor is instrumental in the regulation of lipid metabolism which aids in maintaining balance in energy store.

Pathways

The beta 3 adrenergic receptor is involved in the adrenergic signaling pathways regulating energy expenditure and thermogenesis. These pathways often work together with other adrenergic receptors such as beta 1 and beta 2 receptors. An important pathway involving the beta 3 adrenergic receptor is the cAMP-dependent pathway which influences metabolic functions and energy homeostasis in the body.

The beta 3 adrenergic receptor is associated with obesity and diabetes. Altered function or expression of this receptor can impact the body's ability to regulate energy metabolism leading to these metabolic disorders. The receptor's function has connections with insulin-like growth factor 1 (IGF1) as changes in energy metabolism affect insulin signaling and glucose homeostasis. Abnormal adrenergic receptor activity can also contribute to bladder disorders due to its expression in the urinary system.
