SLC30 refers to a family of genes that encode zinc transporters, which are proteins responsible for moving zinc ions across cell membranes. These transporters play a crucial role in maintaining zinc homeostasis in the body, ensuring that cells have the right amount of zinc for various biological functions. Zinc is an essential trace element involved in numerous processes, including immune function, protein synthesis, and DNA synthesis. Dysregulation of SLC30 transporters can lead to zinc deficiency or toxicity, impacting overall health and contributing to conditions such as diabetes and neurodegenerative diseases.
