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 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 کاملActivation of Radioadaptive Response via Injected Serum of Irradiated Rats with Low Doses of Ionizing Radiation
Introduction: One of the protective concepts in the interpretation of radiation damage in radiobiology is the radioadaptive response. The objective of this present report is to evaluate the induction of radioadaptive response in male rats by injection of pre-irradiated serum with low doses X-radiation intraperitoneally. Materials and Methods: 80 male adul...
متن کاملStructure and activation of muscarinic acetylcholine receptors.
A homology model of the M(1) muscarinic acetylcholine receptor, based on the X-ray structure of bovine rhodopsin, has been used to interpret the results of scanning and point mutagenesis studies on the receptor's transmembrane (TM) domain. Potential intramolecular interactions that are important for the stability of the protein fold have been identified. The residues contributing to the binding...
متن کاملPhosphorylation and Activation of RhoA by ERK in Response to Epidermal Growth Factor Stimulation
The small GTPase RhoA has been implicated in various cellular activities, including the formation of stress fibers, cell motility, and cytokinesis. In addition to the canonical GTPase cycle, recent findings have suggested that phosphorylation further contributes to the tight regulation of Rho GTPases. Indeed, RhoA is phosphorylated on serine 188 (188S) by a number of protein kinases. We have re...
