**Background of SLC39A11 Recombinant Protein**
SLC39A11. a member of the solute carrier family 39 (SLC39A/ZIP), encodes a zinc transporter protein implicated in cellular zinc homeostasis. Zinc, an essential trace element, plays critical roles in enzymatic activity, signal transduction, and gene regulation. The SLC39A family proteins (ZIP transporters) facilitate zinc uptake from extracellular compartments or intracellular vesicles into the cytoplasm, countering the efflux function of SLC30A (ZnT) transporters. SLC39A11. also termed ZIP11. is unique among ZIP members due to its predominantly intracellular localization, particularly in the Golgi apparatus, suggesting a role in regulating organelle-specific zinc distribution.
Structurally, SLC39A11 contains eight predicted transmembrane domains and a histidine-rich motif, a conserved feature in metal transporters that may mediate metal ion binding. While its precise physiological functions remain under investigation, SLC39A11 is hypothesized to influence cellular processes such as proliferation, apoptosis, and immune response. Dysregulation of zinc transporters, including SLC39A11. has been linked to pathologies like cancer, metabolic disorders, and neurodegenerative diseases, highlighting its potential as a therapeutic target.
Recombinant SLC39A11 protein is produced using heterologous expression systems (e.g., mammalian HEK293 or bacterial cells) to enable functional and structural studies. The recombinant form often includes affinity tags (e.g., His-tag, FLAG) for purification via chromatography, followed by validation through SDS-PAGE, Western blot, and mass spectrometry. Its applications span *in vitro* assays to dissect zinc transport kinetics, protein-protein interactions, and post-translational modifications. Researchers also employ it to study SLC39A11’s role in disease models, screen modulators, or resolve 3D structures for drug design. Challenges include maintaining proper folding and post-translational modifications, necessitating optimized expression systems. Overall, recombinant SLC39A11 serves as a vital tool for unraveling zinc biology and its implications in health and disease.
