Protein

P-type cation-transporting ATPase

Gene

PCA1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Cadmium transporting P-type ATPase which plays a critical role in cadmium resistance by extruding intracellular cadmium. Capable of high affinity copper ion binding, but not active copper ion transport. May play a role in copper resistance by chelating and sequestering copper ions.7 Publications

Catalytic activityi

ATP + H2O + Cd2+(In) = ADP + phosphate + Cd2+(Out).

Caution

Although initial characterizations described PCA1 as a copper-transporting ATPase, subsequent experiments have demonstrated that PCA1 is capable of high affinity copper ion binding, but not active copper ion transport.1 Publication
Strain S288C, as well as other laboratory cadmium-sensitive strains, contain a natural Gly-970-Arg mutation which eliminates cadmium transport function. Loss of cadmium resistance provides a fitness advantage under cadmium-free conditions.Curated

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
