Iron metabolism pathway protein

“Iron metabolism pathway proteins” is not a single molecular target but rather refers to a diverse group of proteins and enzymes responsible for the regulation, storage, transport, uptake, and export of iron within the body. Major representatives include **hepcidin** (a peptide hormone regulating systemic iron), **ferroportin** (the main iron exporter), **transferrin receptor** (mediates cellular iron uptake), **ferritin** (iron storage protein), and **iron regulatory proteins** (IRP1/IRP2, which modulate translation of mRNAs for iron metabolism components). Iron metabolism is tightly controlled to balance essential functions such as DNA synthesis, oxidative phosphorylation, and oxygen transport with the toxicity risk presented by excess iron-induced oxidative stress. Dysregulation plays critical pathogenic roles in various diseases including anemia, hemochromatosis, cardiovascular and neurodegenerative disease, and notably, cancer, where tumor cells hijack iron acquisition mechanisms for growth and survival. Iron metabolism proteins are the focus of multiple therapeutic strategies: oral and intravenous iron supplements for deficiency, iron chelators for overload, modulators of the hepcidin-ferroportin axis for iron redistribution, and drugs targeting regulated iron-dependent cell death (ferroptosis) in cancer. Due to the wide variety and interdependence of these proteins, “iron metabolism pathway proteins” is conceptually too broad to be a precise therapeutic target, and disease-directed interventions usually focus on one or a few specific components.
