This study reports the comparative molecular modeling, docking and dynamic simulations of human α9α10 nicotinic acetylcholine receptors complexed with acetylcholine, nicotine and α-conotoxin RgIA, using as templates the ...

The nicotinic acetylcholine receptor (nAChR) is a pentamer of homologous subunits with composition α2βεδ in adult muscle. Each subunit contains four transmembrane domains (M1-M4). Position 8′ of the M3 domain is phenylalanine ...

Nicotinic acetylcholine receptors (nAChRs) are a subfamily of pentameric ligand-gated ion channels with members identified in most eumetazoan clades. In vertebrates, they are divided into three subgroups, according to their ...

Nicotinic acetylcholine receptors can be assembled from either homomeric or heteromeric pentameric subunit combinations. At the interface of the extracellular domains of adjacent subunits lies the acetylcholine binding ...

Aims: Even though the presence of α7 nicotinic receptor (nAChR) in lymphocytes has been demonstrated, its functional role still remains elusive. The aim of our study was to characterize α7 nAChRs in human lymphocytes upon ...

α-Conotoxins (α-CgTxs) are a family of Cys-enriched peptides found in several marine snails from the genus Conus. These small peptides behave pharmacologically as competitive antagonists of the nicotinic acetylcholine ...

Caenorhabditis elegans muscle contains seven different nicotinic receptor (AChR) subunits, five of which have been shown to be components of adult levamisole-sensitive AChRs (L-AChRs). To elucidate the reason for such ...

α4 and β2 nicotinic acetylcholine receptor (nAChR) subunits expressed heterologously assemble into receptors with high (HS) and low (LS) sensitivity to acetylcholine (ACh); their relative proportions depend on the α4 to ...
