From: Retro-miRs: novel and functional miRNAs originating from mRNA retrotransposition
Screening microRNAs (miRNAs) originated by retrotransposition of protein-coding genes. A Summary of databases, datasets, and strategy used to identify retrocopy-derived miRNAs (retro-miRs). B Schematic representation of a parental gene, exonic miRNAs, retrocopies and retro-miRs. All three classes of retro-miRs, exon-junction retro-miRs (EJR-miR, in red), novel retro-miRs (NR-miR, in green), and retroposed retro-miRs (RR-miR, in orange) are represented. Tiny purple bars in retro-miR representations and harpins represent mismatches between them and their respective region in the parental gene
