CC -!- FUNCTION: Protects the cell against copper toxicity by tightly
CC chelating copper ions. May also act as a depository for copper
CC designated for the effective transfer into the apo forms of copper
CC proteins.
CC -!- DOMAIN: Contains 1 metal-binding domain: 6 to 8 copper ions are
CC chelated within a single copper-thiolate cluster and are coordinated
CC via cysteinyl thiolate bridges to 10 cysteine ligands. 6 copper ions
CC are trigonally coordinated, whereas the other 2 are only digonally
CC coordinated.
CC -!- MISCELLANEOUS: There are 2 copies for copper thionein in yeast. The 2
CC identical copies CUP1-1 and CUP1-2 are arranged in tandem.
CC -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 12 family.
CC {ECO:0000305}.
