The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

Structure of the human M2 muscarinic acetylcholine receptor bound to an antagonist
The parasympathetic branch of the autonomic nervous system regulates the activity of multiple organ systems. Muscarinic receptors are G-protein-coupled receptors that mediate the response to acetylcholine released from parasympathetic nerves.

The distribution of charged amino acid residues and the Ca(2+) permeability of nicotinic acetylcholine receptors: a predictive model [PDF]
Nicotinic acetylcholine receptors (nAChRs) are cation-selective ligand-gated ion channels exhibiting variable Ca(2+) permeability depending on their subunit composition.

From ab initio quantum mechanics to molecular neurobiology: A cation-pi binding site in the nicotinic receptor [PDF]
The nicotinic acetylcholine receptor is the prototype ligand-gated ion channel. A number of aromatic amino acids have been identified as contributing to the agonist binding site, suggesting that cation-pi interactions may be involved in binding the ...

Endogenous cholinergic inputs and local circuit mechanisms govern the phasic mesolimbic dopamine response to nicotine [PDF]
Nicotine exerts its reinforcing action by stimulating nicotinic acetylcholine receptors (nAChRs) and boosting dopamine (DA) output from the ventral tegmental area (VTA).
