pfam04096: Nucleoporin2 (This model is not part of the current CDD release)
Nup98-96 autopeptidase S59
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. 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.
