Comments
Talmor-Neiman et al. reported a mature miRNA derived from the 3' arm of this hairpin, and named it miR1210 [1]. A mature miRNA from the 5' arm was named miR473b [2]. This sequence was later determined to be a member of the miR477 family [3], and is therefore renamed here. The mature sequences shown here are the most abundant clones by deep-sequencing [3].
