【 摘 要 】

Non-human primates such as rhesus macaque and cynomolgus macaque are important animals for medical research. These species are classified as Old-World monkeys (Cercopithecidae), in which the immune-related genome structure is characterized by gene duplications. In the present study, we investigated polymorphisms in two genes for ULBP5 encoding ligands for NKG2D. We found 18 and 11 ULBP5.1 alleles and 11 and 13 ULBP5.2 alleles in rhesus macaques and cynomolgus macaques, respectively. In addition, phylogenetic analyses revealed that ULBP5.2 diverged from a branch of ULBP5.1. These data suggested that human ULBP genes diverged from an ancestral gene of ULBP2-ULBP5 and that ULBP6/RAET1L, specifically identified in human, diverged from an ancestral ULBP2 by a recent gene duplication after the diversification of homininae (human and other higher great apes), which were consistent with the findings in our previous analysis of ULBP2 genes in rhesus and cynomolgus macaques.
