Figure 4From: The expansion of the metazoan microRNA repertoireClustalw multiple sequence alignment of mir-421 homologs on the mammalian X chromosome. Additional features (top down): mfe: minimum free energy structure calculated using RNAfold -d2 -noLP, part. func: partition function fold, L2/LINE: direction and position of L2 elements relative to mir-421, mat miRNA: position of mature miRNA, conservat.: conserved positions in sequence alignment.Back to article page
