Do you think this miRNA is real?
Comments
miR-133b was predicted based on comparative analysis of human, mouse and Fugu [1]. It is homologous to miR-133a (MIR:MI0000159 and MIR:MI0000820). The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [3]. The 5' end of the miRNA may be offset with respect to previous annotations.
