**Background of POM121 Antibody**

POM121 (Pore Membrane Protein 121) 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 transmembrane protein, POM121 anchors the NPC to the nuclear membrane and contributes to its structural integrity and functional organization. It interacts with other nucleoporins (e.g., NUP153. NUP98) and plays roles in mitotic NPC disassembly/reassembly and maintaining nuclear envelope architecture.

Antibodies targeting POM121 are vital tools for studying NPC dynamics, nuclear transport mechanisms, and diseases linked to nuclear envelope dysfunction (e.g., cancers, laminopathies). They are widely used in techniques like immunofluorescence, Western blotting, and immunoprecipitation to visualize POM121 localization, assess expression levels, or explore protein interactions. Recent studies highlight POM121's involvement in cellular processes beyond transport, including chromatin organization, gene regulation, and cell cycle control. Dysregulation of POM121 has been implicated in tumor progression and neurological disorders, underscoring its biomedical relevance.

These antibodies also aid in exploring developmental defects or aging-associated NPC alterations. However, specificity validation (e.g., knockout controls) is critical due to potential cross-reactivity with other nucleoporins. Overall, POM121 antibodies remain indispensable for dissecting NPC biology and its connections to human health.
