Comments Information

    • Function

    • Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages. May also have antimicrobial activity.

    • PTM

    • Contains four disulfide bonds 7-23; 10-13; 11-19; 14-22.

Literature Information

  • ·Literature 1

    • Title

    • A new mouse liver-specific gene, encoding a protein homologous to human antimicrobial peptide hepcidin, is overexpressed during iron overload.
