Fig. 8. Sequence alignment of the amino-terminal extracellular domains of rat AChR a1 and a7, GABAAR b1, b2, and b3, and Torpedo AChR a1. Residues boxed in yellow are identical in at least three of the six sequences examined. Underlined regions correspond to the following: 1, predicted signal sequence for each protein; 2, low-affinity BTX-binding site on rat AChRa7 (1); 3, high-affinity BTX-binding sites on Torpedo AChRa1 (2) and rat AChRa7 (1); 4, predicted transmembrane domain for each protein.
