CHRM2 (Cholinergic Receptor Muscarinic 2): CHRM2 is a member of the muscarinic cholinergic receptor family, which plays a crucial role in mediating the effects of acetylcholine in the central and peripheral nervous systems. This G protein-coupled receptor is involved in a variety of physiological functions, including modulation of heart rate, smooth muscle contraction, and cognitive processes. CHRM2's influence on cardiac function makes it a significant factor in cardiovascular regulation, where it contributes to the slowing of heart rate and reduction of cardiac contractility. Additionally, its role in the brain implicates it in memory, learning, and potentially in the pathophysiology of...
