Hepcidin antimicrobial peptide with ferroportin (FPN)

Hepcidin antimicrobial peptide with ferroportin (FPN)
a
SLC40A1 solute carrier family 40 (iron-regulated transporter), member 1 Ferroportin-1, locus: 2q32 [§§] is mediated by the divalent metal transporter, DMT1 and the duodenal iron transporters divalent-metal transporter 1 (SLC11A1). Hemochromatosis genes encode molecules that regulate hepcidin synthesis described for C282Y mutations or TFR2 (transferrin receptor 2) of genes controlling iron metabolism, and two CYBRD1 gene mutations. Hepcidin antimicrobial peptide directly interacts with ferroportin (FPN) and modulates iron transport from macrophages and enterocytes to red blood cell precursors. Ferroportin-1 (SLC11A3) is involved in iron export from enterocytes in mammals, initiated by uptake of ferrous Fe(II) iron across the brush border membrane and localized to the basolateral membrane requires: a glycophosphosinositide-linked, CP gene found in ceruloplasmin and its homologue copper-containing iron oxidase known as (Heph) hephaestin. A mutation in the SLC40A1 genes (Ferroportin) secondary effects of the 'erythropoietic regulator' stimulating intestinal iron absorption from dietary sources, and point mutation in the L ferritin (FTL; 134790) in lens ferritin accumulation contributing to age-related cataract in situations that alter normal iron homeostasis of certain forms of "ferroportin disease" results from dominant negative effects either a regulatory function or as the necessary link in iron homeostasis in health and disease can be interpreted.
