Alignment of Amino Acid Residues in the Three Acetylcholine Binding Proteins from Lymnaea stagnalis (Ls), Aplysia californica (Ac) and Bulinus truncatus (Bt) with the α7 nicotinic receptor from humans. Residue numbering corresponds to Aplysia californica. The black and gray backgrounds correspond to identical and homologous residues in the binding proteins and receptor, respectively, the embolden letters denote identical residues in the three binding proteins. Residues on the principal and complementary faces are denoted.
