Figure 1. Illustration of (α6β2)₂β3 AChR constructs.

A) Diagrammatic representation of an AChR subunit. B) Diagrammatic representation of two AChR subunits joined by a linker. Direction of the linker is indicated by arrows. C) Representation of α6 and α3 sequences used in the α6/α3 chimeras studied. D) Representation of (α6β2)₂β3 AChRs assembled from the various constructs. Agonist binding sites are shown as solid triangles between two subunits. The number and nomenclature for each construct depicted here are used in the following data figures.
