Muscarinic acetylcholine receptor M2 is expressed in the heart and many other tissues. The gene encoding it is localized on human chromosome 7.
Immunogen
GST fusion protein of a part of the i3 intracellular loop of human M2 muscarinic acetylcholine receptor (mAChR) corresponding to amino acid residues 227-356.1, 2
Biochem/physiol Actions
Muscarinic acetylcholine receptor M2 plays an important role in regulating functions of the heart and activities like pain perception and cognition. It is regarded as a good model in GPCR (G protein-coupled receptor) biology pharmacological studies. This receptor has a function in airway remodeling and it enhances the proliferation of airway smooth muscle cells (ASM) which is induced by transforming growth factor-β (TGF-β).
Physical form
Lyophilized at ~0.3 mg/ml from a solution of phosphate-buffered saline, pH 7.4, containing 1% bovine serum albumin, and 0.05% sodium azide.

The cardiac pacemaker sets the heart's primary rate, with pacemaker discharge controlled by the autonomic nervous system through intracardiac ganglia. A fundamental issue in understanding the relationship between neural activity and cardiac chronotropy is the identification of neuronal populations that
Epidemiological studies link organophosphorus pesticide (OP) exposures to asthma, and we have shown that the OPs chlorpyrifos, diazinon and parathion cause airway hyperreactivity in guinea pigs 24 hr after a single subcutaneous injection. OP-induced airway hyperreactivity involves M2 muscarinic receptor
Despite recent advances in crystallography and the availability of G-protein-coupled receptor (GPCR) structures, little is known about the mechanism of their activation process, as only the β2 adrenergic receptor (β2AR) and rhodopsin have been crystallized in fully active conformations. Here
P300 amplitude in childhood predicts substance use disorders by young adulthood. Trajectories of visual P300 amplitude show an association between low amplitude P300 and familial risk for alcohol dependence (AD). Variation in the cholinergic muscarinic receptor gene (CHRM2) has previously

G-protein-coupled receptors (GPCRs) mediate cellular responses to various hormones and neurotransmitters and are important targets for treating a wide spectrum of diseases. Although significant advances have been made in structural studies of GPCRs, details of their activation mechanism remain unclear.
