title: Defending the genome in tudor style.
abstract: Repression of transposable elements is crucial for the survival of germ cells. In this issue of Developmental Cell, Shoji et al. provide evidence that a Tudor domain protein TDRD9 partners with MIWI2 to specifically silence LINE-1 transposons in the fetal germline of male mice.
