Hepcidin inhibits which of the following?
Hepheastin
DMT-1
Cerruloplasmin
Ferropoin
Iron absorption is regulated by hepcidin, a small circulating peptide that is synthesized and released from the liver in response to increases in intrahepatic iron levels. Hepcidin inhibits iron transfer from the enterocyte to plasma by binding to ferropoin and causing it to be endocytosed and degraded.
