The zebra finch FoxP2 3′-UTR contains two miR-9 binding sites and one miR-140-5p binding site. A, The two miR-9 binding sites are 826 and 1472 nt downstream from the stop codon and the miR-140-5p binding site is 51 nt downstream from the stop codon. B, C, The sequences of the miR-9 binding sites and the miR-140-5p binding site are conserved in higher vertebrates. The seed sequences of miR-9 and miR-140-5p and their corresponding binding sites are highlighted in blue.
