WebJan 20, 2024 · With the length of about 26–31 nt, PIWI-interacting RNA (piRNA) is a small non-coding RNA (ncRNA) that interacts with PIWI proteins to form the piRNA silencing complex (piRISC). PIWI is a subfamily of Argonaute, and piRNA must bind to PIWI to exert its regulatory role. Current studies indicated that piRNA and PIWI are significantly … WebJan 27, 2024 · In piRNA biogenesis, piRNA clusters are located in transposon elements. Thus, piRNAs are thought to be involved in transposon silencing through epigenetic mechanisms ( DiGiacomo et al., 2013 ). Transposable elements shift and replicate by inserting themselves into the genome ( Tóth et al., 2016 ).
