Recombinant human transferrin receptor protein (TfR, also abbreviated as TRFP in some contexts) is a genetically engineered form of the transmembrane glycoprotein responsible for cellular iron uptake. The native transferrin receptor binds iron-loaded transferrin in the bloodstream, facilitating its internalization via clathrin-mediated endocytosis. This process is critical for iron homeostasis, impacting erythropoiesis, oxygen transport, and cellular metabolism. Dysregulation of TfR is associated with cancers, neurodegenerative disorders, and anemia.
Recombinant TfR is typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, such as glycosylation, which are essential for ligand-binding activity. It often includes truncated forms (e.g., soluble extracellular domain) for research applications. Purification techniques like affinity tagging (e.g., His-tag) enable high-purity yields.
This protein is widely utilized in drug development (e.g., antibody therapies targeting TfR in cancers), structural studies to elucidate iron-uptake mechanisms, and diagnostic assays for iron-related pathologies. Its recombinant form avoids ethical and batch variability concerns associated with native sources, making it a standardized tool for biomedical research and therapeutic innovation.
