catalytic activity:4 Fe(2+) + 4 H(+) + O(2) = 4 Fe(3+) + 2 H(2)O.,cofactor:Binds 6 copper ions per monomer.,disease:Ceruloplasmin levels are decreased in Wilson disease, in which copper cannot be incorporated into ceruloplasmin in liver because of defects in the copper-transporting ATPase 2.,disease:Defects in CP are the cause of aceruloplasminemia (ACERULOP) [MIM:604290]. It is an autosomal recessive disorder of iron metabolism characterized by iron accumulation in the brain as well as visceral organs. Clinical features consist of the triad of retinal degeneration, diabetes mellitus and neurological disturbances.,function:Ceruloplasmin is a blue, copper-binding (6-7 atoms per molecule) glycoprotein. It has ferroxidase activity oxidizing Fe(2+) to Fe(3+) without releasing radical oxygen species. It is involved in iron transport across the cell membrane.,online information:Ceruloplasmin entry,similarity:Belongs to the multicopper oxidase family.,similarity:Contains 3 F5/8 type A domains.,similarity:Contains 6 plastocyanin-like domains.,tissue specificity:Expressed by the liver and secreted in plasma.,
Secreted. Colocalizes with GCP1 in secretory intracellular compartments. .
Expressed by the liver and secreted in plasma.
