What is the function of metallothionein?
Metallothioneins (MTs) are small cysteine-rich proteins that play important roles in metal homeostasis and protection against heavy metal toxicity, DNA damage, and oxidative stress.
What are the benefits of metallothionein?
Metallothionein, by virtue of its metal ion binding and antioxidant capacity, is able to reduce the damage caused by metal ions and oxidative stress on nerve cells [7,8]. In addition, as an antioxidant, it can protect normal cells from external damage and reduce the risk of cancer [9].
Where is metallothionein found?
Metallothioneins are small proteins that bind to heavy metals such as cadmium, zinc, and copper. They are rich in sulfhydryl groups and can be found in various tissues, including the liver, kidney, and intestine.
What is an example of a metallothionein?
Metallothioneins have diverse metal-binding preferences, which have been associated with functional specificity. As an example, the mammalian Mus musculus MT1 preferentially binds divalent metal ions (Zn(II), Cd(II),...), while yeast CUP1 is selective for monovalent metal ions (Cu(I), Ag(I),...).
