The AP of the Cell Biology Diagrams The nuclear envelope is a dynamic structure that is disassembled and reassembled during 'open' mitosis in higher eukaryotes. These mitotic changes are subject to both spatial and temporal control This review aims at assessing the current understanding of how phosphatases contribute to the remodelling of the nuclear envelope during its disassembling and reformation after cell division and how errors in this process may lead to the development of diseases.
Breakdown and reformation of the nuclear envelope (NE) during cell division is one of the most dramatic structural and functional changes in higher eukaryotic cells. NE breakdown (NEBD) marks a highly regulated switch in chromosome confinement by membranes in interphase to microtubules in M-phase. The boundary of interphase nuclei has a rigid and highly interconnected architecture made up of a The membrane system that encloses genomic DNA is referred to as the nuclear envelope. However, with emerging roles in signaling and gene expression, these membranes clearly serve as more than just a physical barrier separating the nucleus and cytoplasm. Recent progress in our understanding of nuclear envelope architecture and composition has also revealed an intriguing connection between

The nuclear envelope is more than a static barrier between the nuclear and cytoplasmic compartments. It is very dynamic and undergoes extensive remodelling in response to mechanical challenges as The nuclear envelope: form and function The INM, ONM and pore membrane are each intimately associated with distinct proteinaceous structures; these connections ensure the integrity of the nuclear environment and aid in coordinating cellular events. During telophase, the nuclear envelope (NE) reforms around daughter nuclei to ensure proper segregation of nuclear and cytoplasmic contents[-] . NE reformation requires the coating of chromatin by membrane derived from the Endoplasmic Reticulum and a
During cell division, remodeling of the nuclear envelope (NE) enables chromosome segregation by the mitotic spindle[] . The reformation of sealed nuclei requires Endosomal Sorting Complexes Required for Transport (ESCRTs) and LEM2, a transmembrane ESCRT
