Previous GeneCards Identifiers for HAMP Gene
The product encoded by this gene is involved in the maintenance of iron homeostasis, and it is necessary for the regulation of iron storage in macrophages, and for intestinal iron absorption. The preproprotein is post-translationally cleaved into mature peptides of 20, 22 and 25 amino acids, and these active peptides are rich in cysteines, which form intramolecular bonds that stabilize their beta-sheet structures. These peptides exhibit antimicrobial activity against bacteria and fungi. Mutations in this gene cause hemochromatosis type 2B, also known as juvenile hemochromatosis, a disease caused by severe iron overload that results in cardiomyopathy, cirrhosis, and endocrine failure.

GeneCards Summary for HAMP Gene
HAMP (Hepcidin Antimicrobial Peptide) is a Protein Coding gene, and is affiliated with the lncRNA class. Diseases associated with HAMP include Hemochromatosis, Type 2B and Hemochromatosis Type 2. Among its related pathways are TGF-beta signaling pathway (KEGG) and Iron metabolism in placenta. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and ion channel inhibitor activity.
UniProtKB/Swiss-Prot for HAMP Gene
Liver-produced hormone that constitutes the main circulating regulator of iron absorption and distribution across tissues. Acts by promoting endocytosis and degradation of ferroportin, leading to the retention of iron in iron-exporting cells and decreased flow of iron into plasma. Controls the major flows of iron into plasma: absorption of dietary iron in the intestine, recycling of iron by macrophages, which phagocytose old erythrocytes and other cells, and mobilization of stored iron from hepatocytes (PubMed:22306005).
Has strong antimicrobial activity against E.coli ML35P N.cinerea and weaker against S.epidermidis, S.aureus and group b streptococcus bacteria. Active against the fungus C.albicans. No activity against P.aeruginosa (PubMed:11113131, PubMed:11034317).
