WebNov 23, 2024 · Precursors that give rise to piRNAs require specialized transcription and transport machineries because piRNA biogenesis is a cytoplasmic process. The ping-pong cycle, a posttranscriptional silencing mechanism, combines the cleavage-dependent silencing of transposon RNAs with piRNA production. PIWI proteins also function in the … WebThe important role of ribosome biogenesis in cell growth and proliferation has been well documented in bacteria 9 and in yeast 10. Likewise, S6K activation is a plausible mechanism by which the PI ...
