This human miRNA was predicted by computational methods using conservation with mouse and Fugu rubripes sequences [1]. Expression of the excised miR has been validated in zebrafish, and the ends mapped by cloning. Its expression was later verified in human BC-1 cells [3]. There are two predicted hairpin precursor sequences in the human genome; mir-181b-1 (MI0000270) is found on chromosome 1 [1], and mir-181b-2 (MI0000683) on chromosome 9 [2]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
