General Information
Term secondary piRNA processing ID (Ontology) GO:0140965 (Gene Ontology)
Definition A process leading to the generation of a functional secondary piRNA, involving a self-perpetuating piRNA loop, often called the ping-pong cycle, in which piRNAs are amplified by pairing with complementary transcripts (for example the transposable element mRNA target). In Drosophila, the processing involves the piwi proteins aubergine and Argonaute 3 and in mice, the piwi proteins Piwil2 and Piwil4.[ PubMed:29281264 PubMed:32895365 ]
Also Known As "ping-pong derived piRNA" ; "secondary piRNA biogenesis" ; "secondary PIWI-associated RNA processing"
