From: Mechanism and Regulation of Nucleocytoplasmic Trafficking of Smad
The molecular machinery for nuclear import of activated Smad. Shown are Msk/Imp7/8 and the nucleoporins required for nuclear import of Smad, with their relative positions within the NPC indicated. As indicated some of these nucleoporins are located in the cytoplasmic outer ring, the nuclear outer ring, and the nuclear basket sub-structures of the NPC.
