STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

HfeHereditary hemochromatosis protein homolog; Binds to transferrin receptor (TFR) and reduces its affinity for iron-loaded transferrin. (360 aa)    
Predicted Functional Partners:
Tfrc
Transferrin receptor protein 1; Cellular uptake of iron occurs via receptor-mediated endocytosis of ligand-occupied transferrin receptor into specialized endosomes. Endosomal acidification leads to iron release. The apotransferrin-receptor complex is then recycled to the cell surface with a return to neutral pH and the concomitant loss of affinity of apotransferrin for its receptor. Transferrin receptor is necessary for development of erythrocytes and the nervous system (By similarity). Positively regulates T and B cell proliferation through iron uptake (By similarity); Belongs to the [...]

Tfr2
Transferrin receptor protein 2; Mediates cellular uptake of transferrin-bound iron in a non- iron dependent manner. May be involved in iron metabolism, hepatocyte function and erythrocyte differentiation (By similarity).
   
 0.999
B2m
Beta-2-microglobulin; Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
   
 0.993
Hjv
Hemojuvelin; Acts as a bone morphogenetic protein (BMP) coreceptor. Through enhancement of BMP signaling regulates hepcidin (HAMP) expression and regulates iron homeostasis. Belongs to the repulsive guidance molecule (RGM) family.
   
 
 0.992
Hamp
Hepcidin; Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages. May also have antimicrobial activity (By similarity). Belongs to the hepcidin family.
   
  
 0.925
Tmprss6
Transmembrane serine protease 6 (Predicted), isoform CRA_a; Belongs to the peptidase S1 family.
   
  
 0.883
Bmp6
Bone morphogenetic protein 6; Induces cartilage and bone formation.
   
  
 0.848
Slc11a2
Natural resistance-associated macrophage protein 2; May serve to import iron into the mitochondria (By similarity). Important in metal transport, in particular iron. Can also transport zinc, manganese, cobalt, cadmium, copper, nickel and lead. Involved in apical iron uptake into duodenal enterocytes. Involved in iron transport from acidified endosomes into the cytoplasm of erythroid precursor cells. May play an important role in hepatic iron accumulation and tissue iron distribution. Belongs to the NRAMP family.
   
  
 0.818
Slc40a1
Solute carrier family 40 member 1; May be involved in iron export from duodenal epithelial cell and also in transfer of iron between maternal and fetal circulation. Mediates iron efflux in the presence of a ferroxidase (hephaestin and/or ceruloplasmin) (By similarity).
   
  
 0.786
Cybrd1
Cytochrome b reductase 1; Ferric-chelate reductase that reduces Fe(3+) to Fe(2+). Present at the brush border of duodenal enterocytes where it probably reduces dietary Fe(3+) thereby facilitating its transport into the mucosal cells. Uses ascorbate as electron donor. May be involved in extracellular ascorbate recycling in erythrocyte membranes. May also act as a ferrireductase in airway epithelial cells (By similarity).
