CRYSTAL STRUCTURE OF ACHBP FROM BULINUS TRUNCATUS REVALS THE CONSERVED STRUCTURAL SCAFFOLD AND SITES OF VARIATION IN NICOTINIC ACETYLCHOLINE RECEPTORS
OverviewOverview
The crystal structure of acetylcholine-binding protein (AChBP) from the, mollusk Lymnaea stagnalis is the established model for the ligand binding, domains of the ligand-gated ion channel family, which includes nicotinic, acetylcholine, 5-hydroxytryptamine (5-HT3), gamma-aminobutyric acid, (GABA), types A and C, and glycine receptors. Here we present the crystal, structure of a remote homolog, AChBP from Bulinus truncatus, which reveals, both the conserved structural scaffold and the sites of variation in this, receptor family. These include rigid body movements of loops that are, close to the transmembrane interface in the receptors and changes in the, intermonomer contacts, which alter the pentamer stability drastically., Structural, pharmacological and mutational analysis of both ...
