Annotation confidence High
Do you think this miRNA is real?
Mouse mir-320 is predicted [2] based on homology to a cloned miR from human (MIR:MI0000542) [1]. Its expression was later verified in mouse [3]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
