Cellular transporters for zinc.
Nutritionally essential metals such as zinc are moved into and out of cells by a series of transport proteins or transporters. Their tri-fold purpose is to procure zinc from the environment, to protect cells against zinc toxicity, and maintain ample supplies of zinc for metabolic purposes. Two families of zinc transporters are known: the ZIP family that imports zinc and the ZnT family that functions in releasing zinc or sequestering zinc internally.
