Allosteric Modulation of Muscarinic Acetylcholine Receptors
An allosteric modulator is a ligand that binds to an allosteric site on the receptor and changes receptor conformation to produce increase (positive cooperativity) or decrease (negative cooperativity) in the binding or action of an orthosteric agonist (e.g., acetylcholine). Since the identification of gallamine as the first allosteric modulator of muscarinic receptors in 1976, this unique mode ...

متن کاملAllosteric binding sites on muscarinic acetylcholine receptors.
In this issue of Molecular Pharmacology, Tränkle et al. (p. 1597) present new findings regarding the existence of a second allosteric site on the M2 muscarinic acetylcholine receptor (M2 mAChR). The M2 mAChR is a prototypic class A G protein-coupled receptor (GPCR) that has proven to be a very useful model system to study the molecular mechanisms involved in the binding of allosteric GPCR ligan...
متن کاملActivation of muscarinic acetylcholine receptors via their allosteric binding sites.
Ligands that bind to the allosteric-binding sites on muscarinic acetylcholine receptors alter the conformation of the classical-binding sites of these receptors and either diminish or increase their affinity for muscarinic agonists and classical antagonists. It is not known whether the resulting conformational change also affects the interaction between the receptors and the G proteins. We have...
متن کاملSubunit-dependent modulation of kainate receptors by muscarinic acetylcholine receptors.
Interactions between cholinergic and glutamatergic neurotransmitter systems influence synaptic transmission and plasticity. While previous studies have examined cross-talk between acetylcholine (ACh) and NMDA or AMPA receptors, little is known about the effect of ACh on kainate receptors (KARs). We show that stimulation of m1 or m3 muscarinic ACh receptors (mAChRs) for 2min potentiates recombin...
