Annotation confidence High
Do you think this miRNA is real?
miR-7a (previously named miR-7) was predicted by computational methods using conservation between mouse, human and Fugu rubripes sequences [1]. Expression of the excised miR has been validated in zebrafish, and later independently verified in mouse [2]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4]. The ends of the miRNA may be offset with respect to previous annotations.
