Comparison of self-binding affinities of isoforms containing current and ancient exons. A: Distributions of self-binding affinities of isoforms containing exons originating from ancient exon 4 or 9 (conserved isoforms) and those containing exons without such ancient origins (isoforms containing recently acquired exon 4 or 9). Isoforms containing recently gained exons display higher self-binding affinities than conserved isoforms; B: Distributions of self-binding affinities of the ancient and current isoforms. The self-binding affinities of current isoforms are higher than those of ancient isoforms.
