Protein

Copper metallothionein 1-1

Gene

CUP1-1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Protects the cell against copper toxicity by tightly chelating copper ions. May also act as a depository for copper designated for the effective transfer into the apo forms of copper proteins.

Miscellaneous

There are 2 copies for copper thionein in yeast. The 2 identical copies CUP1-1 and CUP1-2 are arranged in tandem.
