Two illustrative maps of the MHC class II region in rhesus macaques. The shortest (A) and longest (B) assembled MHC class II haplotypes are depicted at scale and allele-level resolution. The genes are indicated by colored arrows, which indicate the transcription orientation, with the DR genes in yellow, the DQ genes in blue, and the DP genes in orange. The other genes encoding products that are involved in peptide processing are depicted with gray arrows. Pseudogenes are indicated with a striped pattern. Allele-level information is provided for all 21 resolved MHC class II haplotypes in Supplemental Table S1.
