    Summary
    Enables ferroxidase activity. Involved in intestinal iron absorption; multicellular organismal-level iron ion homeostasis; and positive regulation of iron export across plasma membrane. Acts upstream of or within erythrocyte differentiation. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in basolateral plasma membrane. Orthologous to human HEPH (hephaestin). [provided by Alliance of Genome Resources, Dec 2024]

    1. HEPH and CP are not essential for intestinal iron absorption but are required for proper systemic iron distribution.
      Title: Severe Iron Metabolism Defects in Mice With Double Knockout of the Multicopper Ferroxidases Hephaestin and Ceruloplasmin.
    2. results suggest that ablation of hephaestin and ceruloplasmin could lead to severe systemic iron deficiency and local tissue iron overload, which disrupt the whole body iron homeostasis and impact on tissue functions
      Title: Deletion of hephaestin and ceruloplasmin induces a serious systemic iron deficiency and disrupts iron homeostasis.
    3. Results show that both HEPH and CP are expressed in subcutaneous adipose tissue. Ablation of either MCF leads to a compensatory increase in the other, which contributes to the balance of iron status. However, ablation of both induces severe iron deposition in adipocytes and displays disordered carbohydrate metabolism characterized as type 2 diabetes.
      Title: Ablation of hephaestin and ceruloplasmin results in iron accumulation in adipocytes and type 2 diabetes.
    4. We thus used hephaestin (Heph) and ceruloplasmin (Cp) single-knockout mice and Heph/Cp double-knockout mice to investigate the roles of multicopper ferroxidases(MCF) in pancreatic iron homeostasis. We found that both HEPH and CP were expressed in the mouse pancreas, and that ablation of either MCF had limited effect on the pancreatic iron levels.
      Title: Ceruloplasmin and hephaestin jointly protect the exocrine pancreas against oxidative damage by facilitating iron efflux.
    5. Hephaestin and ceruloplasmin have roles in facilitating iron metabolism in the mouse kidney
      Title: Hephaestin and ceruloplasmin facilitate iron metabolism in the mouse kidney.
    6. In mice with mutation of Cp and Heph, iron accumulates in glia, while neurons have low iron levels. Both neurons and glia degenerate and mice become ataxic unless given an iron chelator.
      Title: Cp/Heph mutant mice have iron-induced neurodegeneration diminished by deferiprone.
    7. The multicopper ferroxidase hephaestin enhances intestinal iron absorption in mice.
      Title: The multicopper ferroxidase hephaestin enhances intestinal iron absorption in mice.
    8. Data (including data from studies in knockout mice) suggest that hephaestin and ceruloplasmin play distinct roles in regulation of gene expression in various regions of the brain and are involved in iron homeostasis.
      Title: Hephaestin and ceruloplasmin play distinct but interrelated roles in iron homeostasis in mouse brain.
    9. Cp and Heph are necessary for iron export from the retina but are not essential for iron import into the retina.
      Title: Ferroxidase hephaestin's cell-autonomous role in the retinal pigment epithelium.
    10. results show that Heph is expressed by oligodendrocytes and plays an important role in iron efflux from these cells.
      Title: Iron efflux from oligodendrocytes is differentially regulated in gray and white matter.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
