Fig. 1From: Mammary gland zinc metabolism: regulation and dysregulationZinc transporting proteins expressed in mammary epithelial cells. Members of the SLC39A family (Zip1-14) import Zn into the cytoplasm, either across the plasma membrane or out of an intracellular compartment. Members of the SLC30A family (ZnT1-10) are responsible for Zn export from the cytoplasm, either across the plasma membrane into the extracellular milieu or into intracellular compartments or organellesBack to article page
