MT3 is a type of protein that plays a crucial role in the regulation of various biological processes in the body. It is part of the MT family, which is known for its involvement in metal ion binding and detoxification. MT3 specifically is found in the brain and is believed to have neuroprotective properties, helping to shield neurons from damage. Research suggests that MT3 may also influence mood and cognitive functions. Its expression can be affected by factors such as stress and neurodegenerative diseases, making it a topic of interest in studies related to mental health and neurology. Understanding MT3 could lead to new insights into brain health and potential therapeutic approaches.
