PIWI-interacting RNAs (piRNAs), a class of conserved non-coding small RNAs, are essential for sex determination, defense against viruses, maintaining genome integrity of diverse animal species. However, many piRNA clusters reside within or close to the heterochromatin, a transcriptional silencing loci. How piRNAs are transcribed remains unknown.
