CC   -!- FUNCTION: Confers resistance to heavy metal ions (e.g. cadmium
CC       (CdCl(2)) and copper (CuCl(2))) by chelating them at the plasma
CC       membrane of root cells, thus stopping their entry and reducing their
CC       accumulation. {ECO:0000269|PubMed:19017626,
CC       ECO:0000269|PubMed:19816106}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:19017626};
CC       Single-pass membrane protein {ECO:0000255}. Secreted, cell wall
CC       {ECO:0000269|PubMed:19017626}.
CC   -!- SIMILARITY: Belongs to the CYSTM1 family. {ECO:0000305}.
