RACK1 associates with muscarinic receptors and regulates M(2) receptor trafficking. [PDF]

PLoS ONE, 2010
Receptor internalization from the cell surface occurs through several mechanisms. Some of these mechanisms, such as clathrin coated pits, are well understood.

Regulation of signal transduction at M2 muscarinic receptor

Physiological Research, 2004
Muscarinic acetylcholine receptors mediate transmission of an extracellular signal represented by released acetylcholine to neuronal or effector cells. There are five subtypes of closely homologous muscarinic receptors which are coupled by means of heterotrimeric G-proteins to a variety of signaling pathways resulting in a multitude of target cell ...

Evidence for M2 and M3 Muscarinic Receptor Involvement in Cholinergic Excitatory Junction Potentials Through Synergistic Activation of Cation Channels in the Longitudinal Muscle of Mouse Ileum

Journal of Pharmacological Sciences, 2013
Cholinergic nerve–mediated excitatory junction potentials (EJPs) in the longitudinal muscle of mouse ileum were characterized by using M2 or M3 muscarinic receptor–knockout (KO) mice and 1-[β-[3-(4-methoxyphenyl)propoxy]-4-methoxyphenethyl]-1H-imidazole ...

Muscarinic receptor regulation of chronic pain-induced atrial fibrillation

Frontiers in Cardiovascular Medicine, 2022
Atrial fibrillation (AF), one of the most common arrhythmias, is associated with chronic emotional disorder. Chronic pain represents a psychological instability condition related to cardiovascular diseases, but the mechanistic linkage connecting chronic ...

Dysfunctional Presynaptic M2 Receptors in the Presence of Chronically High Acetylcholine Levels: Data from the PRiMA Knockout Mouse. [PDF]

PLoS ONE, 2015
The muscarinic M2 receptor (M2R) acts as a negative feedback regulator in central cholinergic systems. Activation of the M2 receptor limits acetylcholine (ACh) release, especially when ACh levels are increased because acetylcholinesterase (AChE) activity

Muscarinic modulation of M and h currents in gerbil spherical bushy cells.

PLoS ONE, 2020
Descending cholinergic fibers innervate the cochlear nucleus. Spherical bushy cells, principal neurons of the anterior part of the ventral cochlear nucleus, are depolarized by cholinergic agonists on two different time scales.

Distribution of Muscarinic Acethylcholine Receptors and Related Signal [PDF]

Türk Biyokimya Dergisi, 2006
Muscarinic receptors are members of G protein coupled receptor family. Molecularcloning studies indicate five intronless genes that encode five muscarinic receptorglycoproteins.

Muscarinic acetylcholine receptor M1 and M3 subtypes mediate acetylcholine-induced endothelium-independent vasodilatation in rat mesenteric arteries

Journal of Pharmacological Sciences, 2016
The present study investigated pharmacological characterizations of muscarinic acetylcholine receptor (AChR) subtypes involving ACh-induced endothelium-independent vasodilatation in rat mesenteric arteries.

The Spinal Muscarinic M1 Receptors and GABAA Receptors Contribute to the McN-A-343–Induced Antinociceptive Effects During Thermal Stimulation of Mice

Journal of Pharmacological Sciences, 2008
The present study was undertaken to clarify how spinal muscarinic receptors are involved in the antinociceptive effects in thermal stimulation. Intrathecal (i.t.) injection of the muscarinic agonist McN-A-343 inhibited the tail-flick response to noxious ...

Allosteric modulation in monomers and oligomers of a G protein-coupled receptor

eLife, 2016
The M2 muscarinic receptor is the prototypic model of allostery in GPCRs, yet the molecular and the supramolecular determinants of such effects are unknown.
