Figure 1. Sequence site and possible relationships of AK005401, FGF21 and YY1. AK005401 is 1392 bp non-coding RNA sequence, which derived from the gene sequence (from 108329474 to 108330865) located on chromosome 12. FGF21 is 947 bp including three exon sequences (from 45,613,890 to 45,615,490) located on chromosome 7. YY1 located on chromosome 12 as like as AK005401 is from 108,793,311 to 108,816,632.
