Small cysteine-rich metal-binding proteins found in the cytoplasm of many eukaryotes. Synthesis can be induced by heavy metals such as zinc, cadmium, copper and mercury, and metallothioneins probably serve a protective function. Metallothionein gene promoters are used in studies of gene expression.
