Angiogenin-induced tRNA-derived stress-induced RNAs promote stress-induced stress granule assembly.
    The Journal of biological chemistry, 2010, Apr-02, Volume: 285, Issue:14

    Angiogenin (ANG) is a secreted ribonuclease that cleaves tRNA to initiate a stress-response program in mammalian cells. Here we show that ANG inhibits protein synthesis and promotes arsenite- and pateamine A-induced assembly of stress granules (SGs). These effects are abrogated in cells transfected with the ANG inhibitor RNH1. Transfection of natural or synthetic 5'- but not 3'-tRNA fragments (tRNA-derived stress-induced RNAs; tiRNAs) induces the phospho-eukaryotic translation initiation factor 2alpha-independent assembly of SGs. Natural 5'-tiRNAs but not 3'-tiRNAs are capped with a 5'-monophosphate that is required for optimal SG assembly. These findings reveal that SG assembly is a component of the ANG- and tiRNA-induced stress response program.
