Transferrin is a plasma protein for iron ion delivery. When a transferrin protein loaded with iron encounters a transferrin receptor on the surface of a cell, it binds to it and is consequently transported into the cell in a vesicle. The cell will acidify the vesicle, causing transferrin to release its iron ions. Each transferrin molecule has the ability to carry two iron ions in the ferric form (Fe3+).

Transferrin levels may be checked in iron deficiency, hemochromatosis and other iron overload disorders. Iron deficiency can refer to: Iron deficiency (plant disorder) Iron deficiency (medicine) This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... Haemochromatosis, also spelled hemochromatosis, is a hereditary disease characterized by improper processing by the body of dietary iron which causes iron to accumulate in a number of body tissues, eventually causing organ dysfunction. ... In medicine, iron overload disorders are diseases caused by the accumulation of iron in the body. ...

Transferrin are also associated with the innate immune system. Transferrin are found in the mucosa and bind iron, thus creating an environment low in free iron, where few bacteria are able to survive. The mucous membranes (or mucosa) are linings of ectodermic origin, covered in epithelium, that line various body cavities and internal organs. ...
