High resolution analysis of mammalian nuclear structure throughout the cell cycle: implications for nuclear pore complex assembly during interphase and mitosis (1).

Canadian Journal of Physiology and Pharmacology | March 1, 2006| | Copyright

Abstract: Nuclear pore complexes (NPCs) are the gateways for both active and passive bidirectional molecular transport between the nucleoplasm and cytoplasm. These mega-dalton assemblies are composed of multiple copies of approximately 30 distinct proteins termed nucleoporins. Higher eukaryotes display an "open" mitosis in which the NPCs, nuclear envelope, and lamina disassemble. During mitosis several nucleoporins are redistributed to kinetochores until they are recruited back to the periphery of chromatin as the NPCs are reassembled. Within this study we have developed and ...
