What Does NPC Stand For?

NPC stands for Nuclear Pore Complex

The Nuclear Pore Complex (NPC) is a large protein structure embedded in the nuclear envelope, serving as a critical gateway that regulates the transport of molecules between the nucleus and the cytoplasm. Composed of multiple proteins called nucleoporins, the NPC facilitates the selective passage of ions, small molecules, and large macromolecules such as RNA and proteins, thereby playing a vital role in maintaining cellular function, gene expression, and overall cellular homeostasis. Its complex architecture allows for both passive diffusion and active transport mechanisms, reflecting its essential role in cellular communication and regulation.
