RhoA-sensitive trafficking of muscarinic acetylcholine receptors.
The clathrin-mediated sequestration pathway is used by non-G protein-coupled receptors (e.g., transferrin receptors) and a large number of G protein-coupled receptors, including beta-2 adrenoceptors and various muscarinic acetylcholine receptor (mAChR) subtypes. Recently, the ubiquitously expressed small GTPase RhoA has been implicated as a negative regulator of transferrin receptor internaliza...
متن کاملInteraction of edrophonium with muscarinic acetylcholine M2 and M3 receptors.
BACKGROUND It has been reported that edrophonium can antagonize the negative chronotropic effect of carbachol. This study was undertaken to evaluate in detail the interaction of edrophonium with muscarinic Mz and M3 receptors. METHODS A functional study was conducted to evaluate the effects of edrophonium on the concentration-response curves for the negative chronotropic effect and the bronch...
متن کاملRACK1 Associates with Muscarinic Receptors and Regulates M2 Receptor Trafficking
Receptor internalization from the cell surface occurs through several mechanisms. Some of these mechanisms, such as clathrin coated pits, are well understood. The M(2) muscarinic acetylcholine receptor undergoes internalization via a poorly-defined clathrin-independent mechanism. We used isotope coded affinity tagging and mass spectrometry to identify the scaffolding protein, receptor for activ...
متن کاملThe role of acetylcholine muscarinic receptors in the rat basolateral amygdala on morphine-induced place preference
Some studies have shown that acetylcholine muscarinic receptors involved in the opiate reward. In the present study, the effect of intra-basolateral amygdale (BLA) acetylcholine muscarinic like receptor agonist (physostigmine) and antagonist (atropine) on the acquisition of morphine-induced place preference has been investigated in male Wistar rats. For this purpose, two 22 gauges guide cannula...
متن کاملReceptor subtype-specific regulation of muscarinic acetylcholine receptor sequestration by dynamin. Distinct sequestration of m2 receptors.
Sustained stimulation of muscarinic acetylcholine receptors (mAChRs) and other G protein-coupled receptors usually leads to a loss of receptor binding sites from the plasma membrane, referred to as receptor sequestration. Receptor sequestration can occur via endocytosis of clathrin-coated vesicles that bud from the plasma membrane into the cell but may also be accomplished by other, as yet ill-...
