CC   -!- FUNCTION: This protein binds cations of several transition elements.
CC   -!- INDUCTION: By cadmium.
CC   -!- DOMAIN: All cysteine residues are arranged in C-X-C groups. These are
CC       thought to be the metal-binding sites in other metallothioneins.
CC   -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 6 family.
CC       {ECO:0000305}.
