SLC39A2 is a gene that encodes a protein involved in the transport of zinc and other metal ions across cell membranes. This protein is part of the SLC (solute carrier) family, which plays a crucial role in maintaining metal ion homeostasis in the body. Proper functioning of SLC39A2 is essential for various biological processes, including cellular signaling and enzyme function. Mutations in the SLC39A2 gene can lead to health issues, particularly affecting the absorption and distribution of zinc. This can result in conditions such as acrodermatitis enteropathica, a disorder characterized by zinc deficiency. Understanding SLC39A2 is important for developing treatments for related disorders and improving overall health.
