Protein
Cobalt uptake protein COT1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Probably responsible for the uptake of cobalt ions. It appears to act in a dosage-dependent manner to counteract the adverse effects of cobalt ions on cells. It may participate in the regulation of cobalt levels under normal physiological conditions and may be important in the supply of metal that is required for metalloenzyme or cofactor synthesis. It reduces the toxicity of cobalt and rhodium ions. Other components responsible for cobalt transport exist.
Similarity
Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. SLC30A subfamily.
