    “…Here we report that the widely used Kc167 cell line, derived from Drosophila melanogaster embryos, expresses piRNAs that are loaded to Aub and Piwi. Kc167 piRNAs are produced by a canonical, primary piRNA biogenesis pathway, from phased processing of precursor transcripts by the Zuc endonuclease, Armi helicase, and dGasz mitochondrial scaffold protein. …”
