Zinc transporters are proteins that help regulate the movement of zinc ions within and between cells. Zinc is an essential mineral that plays a crucial role in various biological processes, including immune function, protein synthesis, and DNA synthesis. These transporters ensure that cells maintain the right levels of zinc, preventing both deficiency and toxicity. There are several types of zinc transporters, categorized mainly into two families: SLC30 (ZnT) and SLC39 (ZIP). The ZnT family typically helps export zinc out of cells, while the ZIP family facilitates zinc uptake. Proper functioning of these transporters is vital for overall health and well-being.
