NRK-EGFP2-Nup50 Cells

The NRK-EGFP2-Nup50 cell line is a clonal stable cell line derived from normal rat kidney (NRK) cells. This cell line was generated through the transfection of a circular plasmid containing the gene encoding the fusion protein of Enhanced Green Fluorescent Protein (EGFP) and Nucleoporin 50 (Nup50), followed by drug resistance selection. As a result, approximately 50% of the cells express the EGFP3-Nup50 fusion protein, which enables the visualization and tracking of Nup50 within the cellular environment. Nup50 is a critical component of the nuclear pore complex, which is responsible for regulating the transport of molecules between the nucleus and cytoplasm. The EGFP3 tag allows for live-cell imaging and other fluorescence-based techniques to study the localization, dynamics, and interactions of Nup50. Despite being a stable cell line, the NRK-EGFP2-Nup50 cells exhibit some variegation, indicating variability in the expression levels of the EGFP3-Nup50 fusion protein among the cells. This cell line is particularly valuable for research focused on nucleocytoplasmic transport, nuclear pore complex dynamics, and the functional role of Nup50 in various cellular processes. The NRK-EGFP2-Nup50 cells are suitable for a range of experimental approaches, including fluorescence recovery after photobleaching (FRAP), fluorescence correlation spectroscopy (FCS), and other advanced microscopy techniques. These studies can provide insights into the molecular mechanisms of nuclear transport and contribute to the understanding of diseases associated with nuclear transport dysfunction, such as certain cancers and neurodegenerative disorders.
