Iron-regulatory hormone that acts as an erythroid regulator after hemorrhage: produced by erythroblasts following blood loss and mediates suppression of hepcidin (HAMP) expression in the liver, thereby promoting increased iron absorption and mobilization from stores. Promotes lipid uptake into adipocytes and hepatocytes via transcriptional up-regulation of genes involved in fatty acid uptake.

1. Erfe(-/-) mice failed to adequately suppress hepcidin expression after infection with Plasmodium berghei K173. Importantly, the sustained production of hepcidin allowed by erythroferrone ablation was associated with decreased parasitemia, providing further evidence that transient iron restriction could be beneficial in the treatment of malaria.

2. The here presented data unearthed EPO-dependent erythroferrone expression acts as an erythropoiesis-driven regulator of iron metabolism under phenylhydrazine-induced hemolytic anemia. PMID: 27067488
3. Erythroferrone contributes to hepcidin suppression and iron overload in a mouse model of beta-thalassemia. PMID: 26276665
4. Compared with wild-type mice, Fam132b-deficient mice exhibited a more severe anemia, had higher hepcidin levels and consequently lower serum iron concentration on days 14 and 21, and manifested impaired mobilization of iron from stores (liver and spleen). PMID: 25193872

Predominantly expressed in skeletal muscle and, at much lower levels, in other tissues, including lung, eye, smooth muscle, heart, brain and kidney. Within skeletal muscles, higher expression levels in soleus as compared with plantaris. Found in blood (at
