The Nuclear Pore Complex and Mitosis
The long-range goal of the Glavy Lab is to outline the molecular mechanisms of the mitotic breakdown of the nuclear pore complex (NPC) with a main focus on the effects of cell cycle dependent modifications on the regulation of nucleoporins (starting with the Nup107-160 subcomplex) and hence the NPC.
The NPC is the principal passageway for nucleocytoplasmic macromolecular traffic. It is composed of about 30 proteins, termed nucleoporins (Nups) designated by their molecular weights in kilodaltons. These are organized into a pseudo-symmetric structure with a two-fold plane quasi-parallel to the nuclear envelope and an eight-fold axis of symmetry across the nucleo-cytoplasmic axis. Most of the Nups are part of a symmetric core structure and therefore occur in at least 16 copies per NPC (e.g. Nup107, Nup133). Others are present only on either the cytoplasmic or the nucleoplasmic side and are present in eight copies per NPC (e.g. Nup358, Nup214, Nup153 also designated FG Nups because of their regional FG (Phe-Gly) sequence repeats). FG Nups are targets of at least nine chromosomal rearrangements found in leukemia, primarily in acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). These chromosomal translocations further effect other related Nups, such as Nup107 and Nup133, demonstrating their interdependence which is critical during cell division.
The NPC is disassembled into subcomplexes of Nups during open mitosis in higher eukaryotic cells. Mitotic disassembly is thought to be triggered by phosphorylation. The best characterized subcomplex is the vertebrate Nup107-160 and the homologous Nup84 subcomplex in Saccharomyces cerevisiae. The Nup107-160 subcomplex has 9 members (Nup160, Nup133, Nup107, Nup96, Nup75, Nup43, Nup37, Seh1 and Sec 13. In the “protocoatomer” hypothesis, this nonameric complex has been proposed to stabilize the sharp bend between the inner and outer nuclear envelope membrane.
