WebMar 20, 2014 · Thus, when Aub:Aub Ping-Pong predominates (Zhang et al, 2011), Ping-Pong amplification appears to consume cluster transcripts less efficiently, consistent with a role for Qin in piRNA precursor processing. Understanding how Qin couples Aub with Ago3 to efficiently generate piRNAs and silence transposons remains a challenge for future studies. WebIn Drosophila, a dense peri-nuclear body, known as Nuage, contains proteins required for the piRNA ping-pong amplification pathway biogenesis, including Aubergine, AGO3, and Tudor. The exact steps and proteins involved in primary and secondary piRNA biogenesis pathways are still under investigation. Suggested Reading
WebJul 31, 2024 · One of the most significant biological discoveries of recent decades is the evidence that almost the whole genome is transcribed [1–3] and that most of the RNA molecules produced are less than 200 nucleotides (nt) long and correspond to multiple classes of small non-coding RNAs.
