Detection of a glycosylated subunit in human serum ferritin.
Ferritin was purified from the serum of two patients with idiopathic haemochromatosis. The protein contained three types of subunit--the H and L subunits of tissue ferritins (although only a trace of H could be detected) and a third subunit, 'G', with the highest apparent molecular weight. Only the 'G' subunit band stained for carbohydrate, indicating that a proportion of the subunits of human serum ferritin are glycosylated. Although serum was obtained from patients with idiopathic haemochromatosis, it is probable that the 'G' subunit is a component of normal serum ferritin.
