tRNA fragments (tRF) are a class of small, regulatory RNAs with diverse functions. 3’-derived tRFs perfectly match long terminal repeat (LTR)-retroelements which use the 3’-end of tRNAs to prime reverse transcription. Recent work has shown that tRFs target LTR-retroviruses and -transposons for the RNA interference (RNAi) pathway and also inhibit mobility by blocking reverse transcription. The highly conserved tRNA primer binding site (PBS) in LTR-retroelements is a unique target for 3’-tRFs to recognize and block abundant but diverse LTR-retrotransposons that become transcriptionally active during epigenetic reprogramming in development and disease. 3’-tRFs are processed from full-length tRNAs under yet unknown conditions and potentially protect many cell types. tRFs appear as an ancient link between RNAi, transposons, and genome stability.
