Hepcidin antimicrobial peptide (HAMP) locus: 19q13 [
§§], is a
25aa-amino-acid
antimicrobial peptide systemic iron
homeostasis depends on by a
furin-dependent process, that disrupt the cell membranes of cellular pathogens. HAMP is most active against gram-positive bacteria also certain yeast and gram-negative species formed by the
defensins as a subfamily of antimicrobially active peptides of animals and plants.
TMPRSS6 as an essential component of a
pathway that detects iron deficiency by controlling HAMP
absorption and its upstream,
USF2 gene. SLC40A1/
ferroportin destroyed by interaction with the (HAMP) peptide, SLC40A1 is the only known transporter that facilitates iron egress.
