Figure 1From: Effect of exonic splicing regulation on synonymous codon usage in alternatively spliced exons of DscamPartial structure of Down syndrome cell adhesion molecule ( Dscam ) in D. melanogaster. Black and gray vertical bars represent mutually exclusive alternatively spliced exons (ASEs) and constitutive exons, respectively. The exon 4, exon 6, and exon 9 clusters consist of 12 (exon 4.1–4.12), 48 (exon 6.1–6.48), and 33 (exon 9.1–9.33) mutually exclusive ASEs, respectively. These ASE clusters are indicated by horizontal bars above the diagram.Back to article page
