Predicting the Impact of Alternative Splicing on Plant MADS Domain Protein Function
Figure 5
Interaction motif architecture of MADS AFFECTING FLOWERING1 (MAF1) isoforms.
Two MADS AFFECTING FLOWERING1 (MAF1) isoforms differ as the result of the selective inclusion of either one of the two mutually exclusive exons (named 5′- and 3′-exon). Only the 5′-exon of the mutually exclusive pair that is included in isoform 1 contains motif A. Both the 5′- and 3′-exons of the mutually exclusive pair have residues at their 3′-boundary that can form interaction motifs (BD or CD) together with the first residues of the downstream constitutively spliced exon. Introns are indicated by horizontal lines.
