HLA-DRB1 May Be Antagonistically Regulated by the Coordinately Evolved Promoter and 3′-UTR under Stabilizing Selection

Linkage Relationship between Promoters, Exon2 and 3′-UTRs.
Branch lengths for all trees are arbitrary, and Bootstrap values larger than 50% are shown on the nodes. The three parts located on the same haplotype were connected with lines. The different color lines denote the deeply separated lineages.
