(cell and molecular biology)
A structure consisting of two membranes that surrounds the nucleus; the outermost membrane is continuous with the rough endoplasmic reticulum.

During open mitosis, when there is no intact nucleus due to the breakdown of the nuclear envelope, importin [alpha]/importin [beta]1 binds to NLS-containing proteins, not to transport them, but to regulate their function.

The geometry of this model is composed of sub domains; extracellular medium cellular membrane cytoplasm nuclear envelope perinuclear space nuclear membrane and nucleus.
Although the function of DAG in signaling pathways is well established, especially at the plasma membrane, its potential contribution to endomem-brane structure (or membrane fusion) mostly derives from in vitro experiments on nuclear envelope assembly (Barona et al., 2005; Larijani and Poccia, 2012).
After DNA replicates, the nuclear envelope surrounding it dissolves.
The nuclear envelope breaks down in late prophase and as homologues attach to microtubules of the QMS, the poles converge in pairs toward a single spindle axis that terminates at opposite cleavage furrows.
This genetic correction repaired the disorganization of the nuclear envelope, and improved overall survival and functioning of the neural stem cells.

Nuclear membrane, along with nuclear lamina on its inner periphery, constitutes the nuclear envelope (NE).
The nuclear envelope is contiguous with another internal cell membrane system: the endoplasmic reticulum.
Lamins A and C, the products of the LMNA gene, ate nuclear intermediate filament proteins and are the major structural components of the lamina network that underlies and supports the nuclear envelope. Nuclear fragility and mislocalization of the nuclear envelope protein emerin are two defects induced by a lack of the A-type lamins.
