Ferritin Protein (Active)

Ferritin is a ubiquitous intracellular protein that stores iron and releases it in a controlled fashion. It is a protein of 450 kDa consisting of 24 subunits that is present in every cell type. In vertebrates, these subunits are both the light (L) and the heavy (H) type with an apparent molecular weight of 19 kDA or 21 kDA respectively; their sequences are about 50% homologous. Ferritin plays a key role in cellular iron metabolism, which includes iron storage and detoxification.It also plays a role in the haemolymph of the polyplacophora where it serves to rapidly transport iron to the mineralizing radula.
