Ferroportin Channel

Meaning

The Ferroportin Channel is a critical transmembrane protein, specifically the sole known cellular iron exporter, responsible for regulating the release of iron from enterocytes, macrophages, and hepatocytes into the systemic circulation. This channel is indispensable for maintaining iron homeostasis throughout the body, directly influencing the availability of iron for erythropoiesis and various metabolic processes. Its proper function is tightly controlled and is a major determinant of iron status, impacting energy levels and hormonal signaling pathways.
