Summary of motifs found in alternative and constitutive exons and flanking introns. Two alternative splice forms are indicated at the top. An alternatively spliced exon for the splice forms is labeled in red while a constitutively spliced exon is labeled in blue. The flanking intron for the alternative and constitutive exon is indicated by the dashed line. The arrows point to representative motifs associated with each of the sequences. Motifs found with respect to the 5' or 3'SS introns flanking constitutive exons are labeled separately.
