Dcr1 tracked down.
RNAi is essential for pericentromeric heterochromatic formation in S. pombe, and although Dcr1, the initiator protein of this process, has been biochemically well described, its subcellular localization has remained elusive. In this issue of Developmental Cell, Emmerth et al. now show that Dcr1 is dynamically shuttling between nucleus and cytoplasm, adding new insight into the subcellular mechanics of RNAi.
