The nuclear pore complex protein plays a role in bidirectional transport across the nucleoporin complex in nucleocytoplasmic transport. The mammalian nuclear pore complex (NPC) is comprised of approximately 30 unique proteins, collectively known as nucleoporins [2]. This entry includes yeast family members such as Nup145p as well as vertebrate Nup98. The NUP C-terminal domains of Nup98 and Nup145 possess peptidase S59 autoproteolytic activity. The autoproteolytic sites of Nup98 and Nup145 each occur immediately C-terminal to the NUP C-terminal domain. Thus, although this domain occurs in the middle of each precursor polypeptide, it winds up at the C-terminal end of the N-terminal cleavage product. Cleavage of the peptide chains are necessary for the proper targeting to the nuclear pore [3].	Domain
