**Background of FTH1 Recombinant Protein**
Ferritin heavy chain 1 (FTH1) is a key subunit of the ferritin complex, a ubiquitous iron-storage protein essential for maintaining cellular iron homeostasis. Ferritin functions as a spherical nanocage composed of 24 subunits, including heavy (FTH1) and light (FTL) chains, which sequester excess iron in a non-toxic, bioavailable form. FTH1 possesses ferroxidase activity, enabling it to oxidize Fe²⁺ to Fe³⁺ for safe storage, thereby protecting cells from iron-induced oxidative damage. Dysregulation of FTH1 is implicated in iron-related disorders, neurodegenerative diseases, and cancer, highlighting its critical role in cellular health.
Recombinant FTH1 protein is produced using genetic engineering techniques, often expressed in *E. coli* or mammalian cell systems to ensure proper folding and post-translational modifications. Its applications span basic research, diagnostics, and therapeutic development. For example, recombinant FTH1 is used to study iron metabolism pathways, explore its antioxidant properties, and model diseases like hemochromatosis or Alzheimer’s, where iron accumulation exacerbates pathology.
In cancer research, FTH1’s dual role as an iron buffer and a regulator of reactive oxygen species (ROS) makes it a target for modulating tumor progression. Some studies suggest that suppressing FTH1 sensitizes cancer cells to ferroptosis, an iron-dependent cell death mechanism, offering potential therapeutic strategies. Additionally, recombinant FTH1 serves as a scaffold in nanotechnology due to ferritin’s innate ability to self-assemble into uniform nanoparticles, enabling drug delivery or vaccine development.
Overall, FTH1 recombinant protein is a versatile tool for deciphering iron biology, disease mechanisms, and innovative biomedical applications, bridging molecular insights with translational potential.
