MT2 is a type of protein that plays a crucial role in the body's metabolism and cellular functions. It is involved in various biochemical processes, including the regulation of gene expression and the transport of essential molecules within cells. This protein is particularly important in the context of metallothioneins, which are proteins that bind metals and help detoxify harmful substances. MT2 is often studied for its potential implications in health and disease, including its role in cancer research and neurodegenerative disorders.
