Title: ADRBK2: A Key Regulator in Asthma and Beyond

Description:

Adrenergic beta-2 receptor kinase 2 (ADRBK2) plays a crucial role in regulating airway function. It phosphorylates the beta-2 adrenoceptor (β2AR), which leads to desensitization and internalization of the receptor, modulating the response to bronchodilators.

Associated Diseases:

• Asthma: ADRBK2 dysfunction has been linked to asthma severity. Polymorphisms in the ADRBK2 gene have been associated with increased risk of severe asthma and impaired response to β2-agonists.
• Chronic Obstructive Pulmonary Disease (COPD): Altered ADRBK2 expression and activity have been observed in COPD patients, contributing to airway inflammation and reduced responsiveness to bronchodilators.
• Cardiac Disorders: ADRBK2 is also involved in heart function, and mutations in the ADRBK2 gene have been associated with arrhythmias and sudden cardiac death.

Did you Know ?

Studies have shown that individuals with certain ADRBK2 polymorphisms are up to 80% more likely to experience severe asthma exacerbations.
