Figure 3From: The nicotinic acetylcholine receptor gene family of the silkworm, Bombyx moriComparison of exon junctions of Bombyx mori and Drosophila melonogaster nAChRs. N-terminal signal leader peptides are symbolized by arrows. Exon junctions are indicated by vertical bars. Sites of transmembrane motifs are indicated by ovals and Cys-loops are showed by triangles. Identical exon boundaries are showed by dotted lines.Back to article page
