Figure 7.
The different repetitive elements associated with DRB6 and DRB5 genes. The macaque (top) and human (bottom) DRB6 (A) and DRB5 (B) genes and their 3′ flanking regions are illustrated. The exons are depicted as arrows. The repetitive elements, which are determined using RepeatMasker, are given and distinguish LTRs (green), LINEs (orange), and SINEs (blue). Macaque DRB6 contains two strong LTR elements, indicated in the boxes: one is located in intron 1, whereas the other one is integrated into its 3′ flanking region. This latter LTR originates from a DRB5 sequence that was present in a shared progenitor.
