Comments

Lagos-Quintana et al. [1] cloned miR-199 from human osteoblast sarcoma cells. They also reported identification of a miRNA from the opposite arm in mouse cells. This sequence was named miR-199-s and the sequence from the 3' arm of the homologous mouse precursor miR-199-as. Lim et al. [2] independently predicted this miRNA computationally using conservation with mouse and Fugu rubripes sequences [2]. Expression of the miR excised from the 5' arm was validated in zebrafish, and the ends mapped by cloning. The excised miR sequences are renamed miR-199a (to avoid confusion with the subsequently identified miR-199b (MIR:MI0000282)) and miR-199a* (from the 3' arm) here. The two putative hairpin precursors in human map to chromosome 19 (mir-199a-1, MIR:MI0000242) and chromosome 1 (mir-199a-2, MIR:MI0000281). Landgraf et al. show that both mature products are expressed, prompting the renaming to miR-199a-5p and miR-199a-3p [4].
