Ferritin structure and function
WebFerritin Structure, Function, and Normal Iron Incorporation. The functions of ferritin are to (1) sequester and store excess ferrous iron, when necessary in large amounts, removing it from the LIP and thus preventing deleterious cellular processes such as ROS generation, protein aggregation, and iron deposition, and (2) to allow release of this ... WebFerritin and hemosiderin are the principal components of nonheme iron present in mammalian tissues, and they account for about 15% of the total amount of iron in the body. 51 The formation of ferritin from apoferritin.

Ferritin is found in most tissues as a cytosolic protein, but small amounts are secreted into the serum where it functions as an iron carrier. Plasma ferritin is also an indirect marker of the total amount of iron stored in the body; hence, serum ferritin is used as a diagnostic test for iron-deficiency anemia .
