Alternatively Spliced Homologous Exons Have Ancient Origins and Are Highly Expressed at the Protein Level
Fig 3
Numbers of peptides detected by ISE type.
In A, boxplot of the five most common splice events (C-terminal substitutions, indels, homologous exon substitutions, N-terminal substitutions and NAGNAG-type splice events) showing the median (thick band) number of peptides per gene, the first and third quartiles (the bottom and top of the boxes). In B, genes binned by the number of peptides detected in the human experiments. Distributions are shown for the 157 genes with homologous exon substitutions (HES) that we identified with BLAST and for those genes that are annotated with at least one splice event (All).
