3'-tRNA Fragments Target Domesticated LTR-Retrotransposons

Matthew Peacey, Joshua I. Steinberg, Andrea J. Schorn

The paper shows 3'-tRNA fragments repress murine LTR-retrotransposons by targeting their tRNA primer binding site, revealing a role in gene regulation.

HENMT1 restricts endogenous retrovirus activity by methylation of 3'-tRNA fragments

Joshua I. Steinberg, Helene Sertznig, John J. Desmarais…·Andrea J. Schorn

This study identifies HENMT1 as a methyltransferase that protects 3'-tRNA fragments from degradation, enhancing their ability to silence endogenous retroviruses.
