Position of the domain sequences relative to introns. (Neighbor) Domains are encoded by exons separated by one intron, (farther) domains are encoded by exons separated by one or more exons and two or more introns, (same) domains are encoded by the same exon. (A) Seventy-five class II pairs of the vertebrates (Table 2) were found in 143 gene models in the human genome. The relative position of the domain sequences in these gene models is summarized. Details of the data are given in Supplemental Table 5. (B) Thirty-one class II pairs of the chordates (Table 4) were found in 76 gene models in the human genome. The relative position of the domain sequences in these gene models is summarized. Details of the data are given in Supplemental Table 7.
