tRNA modifications: necessary for correct tRNA-derived fragments during the recovery from stress?

Bioessays. 2013 Apr;35(4):323-7. doi: 10.1002/bies.201200158. Epub 2013 Jan 11.

Abstract

Endonuclease-mediated tRNA fragmentation has been observed in many species suggesting functional importance for tRNA fragments. The size distribution of tRNA-derived fragments indicates the existence of mechanisms that protect tRNAs and their fragments from total degradation by exonucleases. Could post-transcriptional modifications be important for the controlled processing of tRNAs?
