Fig. 1From: A human specific Alu DNA cassette is found flanking the genes of transcription factor AP2Mapping of the polymorphic HK1 Alu. The polymorphic Alu (HK1) is located in the flanking region of TFAP2B and TFAP2D genes. The HK1 Alu is flanked by 2 other Alu elements (HK2 and HK3) that are human specific and in opposite orientation to HK1Back to article page
