NUP153 is a key component of the nuclear pore complex (NPC), a large protein assembly embedded in the nuclear envelope that regulates nucleocytoplasmic transport. As a nucleoporin, NUP153 is localized to the nuclear side of the NPC, forming part of the nuclear basket structure. It plays critical roles in mediating the transport of macromolecules between the nucleus and cytoplasm, interacting with transport receptors like importins and exportins. Additionally, NUP153 is involved in chromatin organization, gene regulation, and mitotic progression. Its dynamic phosphorylation during mitosis facilitates NPC disassembly and reassembly.
NUP153 antibodies are essential tools for studying the function and localization of this protein in cellular processes. These antibodies are widely used in techniques such as immunofluorescence, Western blotting, and immunoprecipitation to investigate NPC architecture, nuclear transport mechanisms, and NUP153's role in diseases. Dysregulation of NUP153 has been linked to cancers, viral infections (e.g., HIV), and neurodegenerative disorders, making its antibodies valuable for both basic research and clinical applications. Most NUP153 antibodies are raised against specific epitopes, often in rabbits or mice, and validated for specificity using knockout controls or siRNA knockdown. Their utility extends to exploring interactions with viral capsids, chromatin modifiers, and cell cycle regulators, underscoring NUP153's multifaceted roles in cellular homeostasis.
