nuclear envelope organization

Definition

Target type: biologicalprocess

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nuclear envelope. [GOC:dph, GOC:ems, GOC:jl, GOC:mah]

The nuclear envelope (NE) is a double-membrane structure that surrounds the nucleus of eukaryotic cells. It plays a crucial role in regulating the passage of molecules between the nucleus and cytoplasm, and in maintaining the structural integrity of the nucleus. The NE is composed of two membranes, the inner nuclear membrane (INM) and the outer nuclear membrane (ONM), separated by a perinuclear space. The ONM is continuous with the endoplasmic reticulum (ER) and is studded with ribosomes. The INM is associated with the nuclear lamina, a meshwork of intermediate filaments that provides structural support to the nucleus.

The process of nuclear envelope organization is complex and involves a number of different steps, including:

1. **Nuclear pore complex assembly:** The nuclear pore complex (NPC) is a large protein structure that spans the NE and regulates the passage of molecules between the nucleus and cytoplasm. NPC assembly begins during the early stages of NE formation and is completed after nuclear division.

2. **Nuclear lamina assembly:** The nuclear lamina is a meshwork of intermediate filaments that provides structural support to the nucleus and plays a role in regulating gene expression. Lamina assembly begins during the late stages of NE formation and is completed after nuclear division.

3. **Chromatin association with the INM:** The INM is associated with the nuclear lamina and also with chromatin, the genetic material of the cell. This association helps to organize the chromatin within the nucleus and plays a role in gene expression.

4. **Nuclear membrane fusion:** During nuclear division, the NE breaks down and then reforms around the newly replicated chromosomes. This process involves the fusion of membrane vesicles derived from the ER.

5. **NE dynamics and regulation:** The NE is a dynamic structure that can change its shape and size in response to cellular needs. For example, during mitosis, the NE breaks down and then reforms around the newly replicated chromosomes. The NE is also regulated by a number of different signaling pathways.

The process of nuclear envelope organization is essential for the proper functioning of the cell. Disruptions to this process can lead to a number of different diseases, including cancer and neurodegenerative diseases.'
