Intranuclear dynamics of the Nup107-160 complex
Nup98 is a glycine-leucine-phenylalanine-glycine (GLFG) repeat-containing nucleoporin that, in addition to nuclear transport, contributes to multiple aspects of gene regulation. Previous studies revealed its dynamic localization within intranuclear structures known as GLFG bodies. Here we show that the mammalian Nup107-160 complex (Y-complex), a major scaffold module of the nuclear pore, togeth...
متن کاملThe Conserved Nup107-160 Complex Is Critical for Nuclear Pore Complex Assembly
Nuclear pore complexes (NPCs) are large multiprotein assemblies that allow traffic between the cytoplasm and the nucleus. During mitosis in higher eukaryotes, the Nuclear Envelope (NE) breaks down and NPCs disassemble. How NPCs reassemble and incorporate into the NE upon mitotic exit is poorly understood. We demonstrate a function for the conserved Nup107-160 complex in this process. Partial in...
متن کاملThe Nup107-160 nucleoporin complex is required for correct bipolar spindle assembly.
The Nup107-160 complex is a critical subunit of the nuclear pore. This complex localizes to kinetochores in mitotic mammalian cells, where its function is unknown. To examine Nup107-160 complex recruitment to kinetochores, we stained human cells with antisera to four complex components. Each antibody stained not only kinetochores but also prometaphase spindle poles and proximal spindle fibers, ...
متن کاملCell-cycle-dependent phosphorylation of the nuclear pore Nup107-160 subcomplex.
The nuclear pore complex (NPC) mediates macromolecular transport between the nucleus and the cytoplasm. Many NPC proteins (nucleoporins, Nups) are modified by phosphorylation. It is believed that phosphorylation regulates the breakdown of the nuclear envelope at mitosis and the disassembly of the NPC into different subcomplexes. In this study, we examined the cell-cycle-dependent phosphorylatio...
متن کاملThe human Nup107-160 nuclear pore subcomplex contributes to proper kinetochore functions.
We previously demonstrated that a fraction of the human Nup107-160 nuclear pore subcomplex is recruited to kinetochores at the onset of mitosis. However, the molecular determinants for its kinetochore targeting and the functional significance of this localization were not investigated. Here, we show that the Nup107-160 complex interacts with CENP-F, but that CENP-F only moderately contributes t...
