Structure of an iron-transport protein revealed

20 octubre 2014

Iron is the most abundant trace element in humans. As a cofactor of certain proteins, it plays an essential role in oxygen transport and metabolism. Due to the major importance of iron in a wide variety of cellular processes, and the harm caused by its uncontrolled accumulation in the body, its uptake and storage is strictly regulated. In mammals, iron is imported into cells by the membrane transport protein DMT1. Mutations of DMT1, which affect its transport properties, lead to iron-related metabolic disorders such as anemia and the iron storage disease hemochromatosis.
