Iron is an essential element for almost all living beings. Ferroportin is the only known cellular iron exporter and is responsible for maintaining iron homeostasis. The hepcidin-ferroportin axis is central to iron regulation. Dysregulation of ferroportin is thus associated with iron disorders. Understanding how ferroportin is regulated will provide greater insight into iron metabolism and potential therapies for iron-related disease. This review synthesizes current knowledge on ferroportin biology with a particular focus on its regulatory modulators and their therapeutic potential and provides an updated perspective on the molecular pathogenesis and clinical spectrum of ferroportin disease. Elucidating these mechanisms will be essential for the development of targeted interventions to correct iron dysregulation in diverse human diseases.
