The translocation of the DFF complex from the cytoplasm to the nucleus is mediated by the importin alfa/beta heterodimer. Both DFF40 and DFF45 possess NLS at their C-termini that interact directly with the importin alfa/beta heterodimer. However, DFF complex binds more tightly compared with the individual subunits and C-termini of both subunits are required for DFF nuclear import (Neimanis et al., 2007).
