Comparison of the SIGLEC11 and SIGLEC16 genes. a Gene structures of SIGLEC11 and SIGLEC16. Exons of SIGLEC11 and SIGLEC16 are represented by solid and open boxes, respectively. The regions with similarity between SIGLEC11 and SIGLEC16 are indicated with a light shadow (A/A’) and a dark shadow (B/B’). b Sliding window analysis of the conservation profile of SIGLEC11 versus SIGLEC16 (window size 20 bp; step size 1 bp). The ~2-kb genomic region shows consistently high sequence identity (97%–99%) between SIGLEC11 and SIGLEC16 in every species, and is designated the Ac/Ac’ region. On the other hand, the ~400-bp genomic region shows consistently lower identity in the similar region of every species, and is designated the Bc/Bc’ region
