Possible roles of piRNAs
| piRNAs | Functions | Ref. |
|---|---|---|
| ncRNAs bind to PIWI subfamily Argonaute proteins | Epigenetic changes in germ cell lines | [61,63-66] |
| piRNA/PIWI complex | Transposon silencing heterochromatin modification | [67,68] |
| piRNAs | DNA methylation of transposons and specific genes | [69,70] |
| Degradation of retrotransposon- linked mRNA | [71] |
piRNA: p-element induced Wimpy testis RNA; mRNA: messenger RNA; ncRNAs: non-coding RNAs
