The beta-1 adrenergic receptor1 adrenoreceptor), also known as ADRB1, is a beta-adrenergic receptor, and also denotes the human gene encoding it.[1] It is a G-protein coupled receptor associated with the Gs heterotrimeric G-protein and is expressed predominantly in cardiac tissue.



Actions of the β1 receptor include:


Isoprenaline has higher affinity for β1 than adrenaline, which, in turn, binds with higher affinity than noradrenaline at physiologic concentrations. Selective agonists to the beta-1 receptor are:


(Beta blockers) β1-selective ones are:


Gs renders adenylate cyclase activated, resulting in increase of cAMP.


Specific polymorphisms in the ADRB1 gene have been shown to affect the resting heart rate and can be involved in heart failure.[1]


Beta-1 adrenergic receptor has been shown to interact with DLG4[5] and GIPC1.[6] Interaction between testosterone and β-1 ARs have been shown in anxiolytic behaviors in the basolateral amygdala.[7]
