Comparison of Bmα4, Bmα5, and their truncated transcripts. Missed exons are displaced by bridge lines. N-terminal signal leader peptides are symbolized by arrows. Exon junctions are indicated by vertical bars. Sites of transmembrane motif are indicated by ovals and Cys-loops are showed by triangles. Identical exon boundaries are showed by dotted lines. A short bar downstream of the bridge line of truncated Bmα5 indicates a premature stop codon because of a frame shift.
