**Background of TFRC Recombinant Protein**
The transferrin receptor 1 (TFRC), also known as CD71. is a transmembrane glycoprotein critical for cellular iron uptake. It binds to iron-loaded transferrin in the bloodstream, facilitating its internalization via receptor-mediated endocytosis. This process is essential for maintaining iron homeostasis, as iron is a cofactor for numerous biological processes, including oxygen transport, DNA synthesis, and energy production. Dysregulation of TFRC expression is linked to diseases such as cancer, anemia, and neurodegenerative disorders, highlighting its physiological and pathological significance.
Recombinant TFRC protein is produced through genetic engineering, typically using mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, such as glycosylation. The purified protein retains the functional domains of native TFRC, including its extracellular domain responsible for transferrin binding, enabling its use in structural studies, ligand interaction assays, and therapeutic development.
In research, TFRC recombinant protein serves as a tool to study iron metabolism, cancer biology, and receptor trafficking mechanisms. It is also exploited in drug discovery, particularly for targeting iron-dependent cancers, where TFRC is often overexpressed. Additionally, it aids in developing antibody-based therapies, diagnostic kits, and nanoparticle drug delivery systems that leverage TFRC-mediated endocytosis for targeted treatment.
Overall, TFRC recombinant protein bridges fundamental research and clinical applications, offering insights into iron-related diseases and advancing therapeutic strategies. Its versatility underscores its importance in both academic and industrial biomedical research.
