As part of a FlyBase and GO consortium project focused on ncRNAs, we have created GO terms to annotate Piwi-interacting RNA (piRNA).
- GO:0140990 primary piRNA processing
- GO:0140965 secondary piRNA processing,
- GO:0141006 piRNA-mediated retrotransposon silencing by heterochromatin formation
- GO:0141009 piRNA-mediated retrotransposon silencing by mRNA destabilization
You can view current annotations on AmiGO (https://amigo.geneontology.org/amigo/term/GO:0140990). We welcome any feedback from the community to improve the coverage and accuracy of these (and all other) annotations and GO terms.
