RT "Purification and characterization of a cadmium-induced metallothionein
RT from the shore crab Carcinus maenas (L.).";
RL Biochem. J. 297:609-614(1994).
CC -!- FUNCTION: Metallothioneins have a high content of cysteine residues
CC that bind various heavy metals. Class I MTS in marine crustacea are
CC involved in the sequestration of elevated levels of heavy-metal ions.
CC -!- INDUCTION: By cadmium.
CC -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 3 family.
CC {ECO:0000305}.
