'''The crystal structure of the N-terminal domain of Nup133 reveals a beta-propeller fold common to several nucleoporins'''<br />


==Overview==
==The crystal structure of the N-terminal domain of Nup133 reveals a beta-propeller fold common to several nucleoporins==
Nucleocytoplasmic transport occurs through nuclear pore complexes (NPCs), whose complex architecture is generated from a set of only approximately, 30 proteins, termed nucleoporins. Here, we explore the domain structure of, Nup133, a nucleoporin in a conserved NPC subcomplex that is crucial for, NPC biogenesis and is believed to form part of the NPC scaffold. We show, that human Nup133 contains two domains: a COOH-terminal domain responsible, for its interaction with its subcomplex through Nup107; and an, NH2-terminal domain whose crystal structure reveals a seven-bladed, beta-propeller. The surface properties and conservation of the Nup133, beta-propeller suggest it may mediate multiple interactions with other, proteins. Other beta-propellers are predicted in a third of all, nucleoporins. These and several other repeat-based motifs appear to be, major elements of nucleoporins, indicating a level of structural, repetition that may conceptually simplify the assembly and disassembly of, this huge protein complex.
