A gene for adrenaline signalling

The fight-or-flight hormone, adrenaline, functions as a signalling molecule by binding to a protein coded for by the ADBR2 gene (beta-2 adrenergic receptor). This receptor plays a key role in skeletal muscle, cardiovascular, respiratory, metabolic and hormonal systems. ADRB2_1 genetic variations are related to levels of the ADBR2 receptor.
