Annotation confidence High
Do you think this miRNA is real?
Kim et al. cloned 40 new miRNAs from rat E18 primary cortical neurons, including the sequence identical to the miRNA cloned from the reverse strand of mouse let-7d (MIR:MI0000405), named let-7* [1]. The predicted precursor sequence from a newer assembly of the rat genome also contains the let-7d sequence in the 5' arm. The let-7d* sequence published in [1] had an extra 3' A residue, which conflicts with the sequence of the precursor shown here. 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.
