Annotation confidence Not enough data
Do you think this miRNA is real?
Mouse miR-302b was verified experimentally by Mineno et al using MPSS technology [1]. The MPSS protocol used provides 22nt sequences, but the true extents of the mature miRNA are not reliably obtained. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [2]. The 5' end of the miRNA may be offset with respect to previous annotations.
