Coupled protein synthesis and ribosome-guided piRNA processing on mRNAs

Abstract

Ribosome can mediate piRNA biogenesis from long non-coding RNAs following translation of the short open reading frames. Here the authors show that 80S ribosome also guides piRNA production from 3’ UTR of protein-coding genes after translation of long open reading frames, indicating a general piRNA biogenesis mechanism regardless of their precursor ORF length.
