Copper transporters are specialized proteins that help move copper ions within cells and throughout the body. Copper is an essential trace element necessary for various biological functions, including energy production and the formation of red blood cells. These transporters ensure that copper is delivered to the right locations, preventing both deficiency and toxicity. There are several types of copper transporters, including ATP7A and ATP7B, which play crucial roles in copper absorption and excretion. Mutations in these transporters can lead to disorders such as Menkes disease and Wilson's disease, highlighting their importance in maintaining copper homeostasis.
