Integration of the MIR and AluSp elements in the BLOC1S2 gene during primate evolution. a Gene structure of the crab-eating monkey BLOC1S2 gene and primer location. b PCR amplification of the MIR and AluSp elements in several primates. M indicates the size marker, and the primate names are abbreviated as follows. HU: human; CH: chimpanzee; GI: gibbon; RH: rhesus monkey; CR: crab-eating monkey; AGM: African green monkey; CO: colobus monkey; MA: marmoset; SQ: squirrel monkey; and LE: ring-tailed lemur. c Schematic representation of the integration event of MIR and AluSp into the BLOC1S2 gene during primate evolution. Green and yellow arrow boxes represent the AluSp and MIR elements, respectively. Mya: millions of years ago
