Muscarinic Acetylcholine Receptor M3 (M AChr) ELISA Kit for Human

The muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system. The muscarinic cholinergic receptor 3 controls smooth muscle contraction and its stimulation causes secretion of glandular tissue. [provided by RefSeq, Jul 2008]

mAChR M3: The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover. Defects in CHRM3 are the cause of Eagle-Barrett syndrome (EGBRS). EGBRS is a syndrome characterized by thin abdominal musculature with overlying lax skin, cryptorchism, megacystis with disorganized detrusor muscle, and urinary tract abnormalities. Belongs to the G-protein coupled receptor 1 family. Muscarinic acetylcholine receptor subfamily. CHRM3 sub-subfamily.
