Recombinant human NUPL2 (Nucleoporin-like 2) protein is a biologically engineered version of the naturally occurring NUPL2 protein, which belongs to the nucleoporin family involved in nucleocytoplasmic transport. NUPL2. also known as NUP50. is a component of the nuclear pore complex (NPC), a critical structure regulating molecular trafficking between the nucleus and cytoplasm. It contains distinct domains, including an N-terminal α-helical region and a C-terminal FG (phenylalanine-glycine) repeat domain, which facilitate interactions with transport receptors like importins and exportins. NUPL2 plays roles in mitotic progression, mRNA export, and chromatin organization, with studies linking its dysfunction to cellular senescence and cancer.
Recombinant NUPL2 is typically produced in expression systems (e.g., *E. coli* or mammalian cells*) using genetic engineering to ensure proper folding and post-translational modifications. This protein serves as a vital tool for *in vitro* studies, such as elucidating NPC assembly mechanisms, modeling nuclear transport dysregulation in diseases, or screening therapeutic agents targeting nucleoporin-related pathologies. Its applications extend to structural biology (e.g., cryo-EM studies) and functional assays exploring interactions with viral proteins or oncogenic factors. Further research on recombinant NUPL2 may advance understanding of cellular aging, cancer metastasis, and viral pathogenesis.
