CRYSTAL STRUCTURE OF APO ACHBP FROM APLYSIA CALIFORNICA
Overview
Upon ligand binding at the subunit interfaces, the extracellular domain of, the nicotinic acetylcholine receptor undergoes conformational changes, and, agonist binding allosterically triggers opening of the ion channel. The, soluble acetylcholine-binding protein (AChBP) from snail has been shown to, be a structural and functional surrogate of the ligand-binding domain, (LBD) of the receptor. Yet, individual AChBP species display disparate, affinities for nicotinic ligands. The crystal structure of AChBP from, Aplysia californica in the apo form reveals a more open loop C and, distinctive positions for other surface loops, compared with previous, structures. Analysis of Aplysia AChBP complexes with nicotinic ligands, shows that loop C, which does not significantly change conformation upon, ... [(full description)]
