Web15 mrt. 2024 · Hepcidin main mode of action is realized through its binding with ferroportin (FPN) in target cells, like enterocytes, macrophages, hepatocytes (Fig. 1). FPN is the major protein channel that regulates iron export from cells. Its complex with hepcidin induces FPN degradation inside cells (Nemeth et al. 2004). WebIn the adult, the liver-derived hormone hepcidin (HAMP) controls systemic iron levels by blocking the iron-exporting protein ferroportin (FPN) in the gut and spleen, the sites of iron absorption and recycling, respectively. Impaired HAMP expression or FPN responsiveness to HAMP result in iron overload. HAMP is also expressed in the fetal liver ...

Ferroportin-1, also known as solute carrier family 40 member 1 (SLC40A1) or iron-regulated transporter 1 (IREG1), is a protein that in humans is encoded by the SLC40A1 gene, and is part of the Ferroportin (Fpn) Family (TC# 2.A.100). Ferroportin is a transmembrane protein that transports iron from the inside of a cell to the outside of the cell. Ferroportin is the only known iron exporter.
