P.333 left column top paragraph:"The NPC consists of several major domains (Fig. 1): the selective central channel, or central transporter region the core scaffold that supports the central channel the transmembrane regions the nuclear basket and the cytoplasmic filaments [ref 5]. The central channel is filled and surrounded with a distinct class of Nup [nucleoporin] that has numerous large domains rich in phenylalanine and glycine repeats, termed FG Nups. It is this central channel and the FG Nups that seem sufficient to mediate selective receptor-mediated transport [refs 6, 7]. The nuclear basket consists of eight filaments that reach into the nucleoplasm, attached to each other by a ring at the end. Electron microscopy tomographs have shown that filaments extend from this basket into the nucleus [refs 8, 9]. The cytoplasmic filaments are less ordered, forming highly mobile molecular rods projecting into the cytoplasm. The reach of NPCs can extend about 100 nm into the nucleus and cytoplasm [primary sources]." |
