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 83aa, rat/human 84aa) are almost exclusively produced in liver.
Human hepcidin is produced from 84aa precursor, including a putative 24aa signal peptide.
The secreted form of hepcidin in blood and urine consists of C-terminal 20, 22 or 25aa residues.
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 upregulated by lipopolysaccharides (LPS).
Applications:Suitable for use in ELISA.
Western Blot, though not tested, may potentially be used as an application.
ELISA: 1:100,000 using 50-100ng control peptide/well
