Nucleofinin

Nucleofinin is a protein found in the nucleus of eukaryotic cells. It plays a critical role in the process of nuclear envelope assembly during cell division and is also involved in maintaining nuclear organization and function. Nucleofinin is a component of the inner nuclear membrane and is essential for the proper formation and integrity of the nuclear envelope. It interacts with other proteins that are crucial for building the nuclear membrane, helping to recruit them to the correct location. This protein is particularly important during mitosis, when the nuclear envelope breaks down and then reforms around the separated chromosomes. Research suggests that nucleofinin's function extends beyond just structural support. It may also be involved in regulating gene expression and responding to DNA damage. Its precise mechanisms of action are still an active area of scientific investigation, but its fundamental importance in nuclear biology is well-established.
