A zinc transporter is a type of protein that helps move zinc ions in and out of 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, which is vital for overall health. There are several types of zinc transporters, categorized mainly into two families: SLC39 (ZIP) and SLC30 (ZnT). The ZIP transporters generally facilitate the uptake of zinc into cells, while the ZnT transporters help export excess zinc out of cells. Proper functioning of these transporters is important for preventing zinc deficiency and toxicity.
