Zinc transporters are specialized proteins that help regulate the movement of 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, preventing both deficiency and toxicity. There are several types of zinc transporters, categorized mainly into two families: SLC30 and SLC39. Each family has different functions and mechanisms for transporting zinc. Proper functioning of these transporters is vital for overall health, as imbalances can lead to various health issues, including zinc deficiency and related diseases.
