Highly polymorphic STR marker amplified with human DYS389 primers in Japanese macaques (Macaca fuscata).
Amplification products from male and female Japanese macaques were obtained by PCR with human Y-chromosomal DYS389 primers. These products were examined by electrophoresis and sequence analysis. The PCR products from the 12 Japanese macaques tested had different band patterns on an electrophoretogram. Sequence analysis of the products revealed that the high polymorphism originated from variable numbers of repeats of two separate CTAT sequences. The sequences of the Japanese macaque products were similar to those of the reference human DYS389 sequence. However, variable CTGT repeats and a difference in the second forward primer binding site yielded two products in human males, DYS389I and DYS389II, which do not exist in Japanese macaques. Our results suggest that the human DYS389 primers may be a potential tool not only for distinguishing between human and Japanese macaque DNA samples, but also for identifying individual macaques, because of the highly polymorphic alleles.
