Definition of metallothionein:
Protein involved in cel detoxification mechanisms for various heavy metals.[1]
This is the common definition for metallothionein, other definitions can be discussed in the article

Notes
Metallothioneins occur in almost all organisms. They can regulate heavy metal concentrations by binding them. Organisms can produce metalollothioneins in response to the presence of heavy metals. However, when the amount of heavy metals exceeds the amount the metallothioneins can handle, the toxic effects of the contaminants will be manifested.[2] Metallothionein induction gradually increases the tolerance of an organism to metal toxicity.
