Hepcidin (Hepc, hepatic bactericidal protein) or LEAP (liver expressed antimicrobial peptide) is small, cysteine-rich peptide, antimicrobial peptide similar to defensins and thionins.
Hepcidin (unprocessed, proprotein in mouse 83 aa, rat/human 84 aa) are almost exclusively produced in liver.
Human hepcidin is produced from 84-aa precursor, including a putative 24-aa signal peptide.
The signal peptide is cleaved to produce pro-HEPC, which is further processed to generate the mature secreted form of hepcidin (C-terminal 20, 22 or 25-aa HEPC).
In humans, 20-aa and 25-aa appears to be the major HEPC secreted peptides with antimicrobial activities.
The three secreted HEPC alternatively spliced HEPC peptides differ at the N-terminus
The link between hepcidins and iron metabolism is that hepcidin expression is abolished in mice exhibiting iron-overload due to the targeted disruption of USF2 (upstream stimulatory factor 2) gene resembling the situation in hfe-/- mice.
The human gene is located at chromosome 19, in close proximity with Usf2 gene.
Hepcidin levels are increased in iron loading and in beta-2 microglobulin knockout mice.
Hepcidins are devoid of IRE.
Like other antimicrobial peptides, hepcidin is up-regulated by lipopolysaccharides (LPS).
