Abstract
Copper is an important cofactor in numerous biological processes in all living organisms. However, excessive copper can be extremely toxic, so it is vital that the copper level within a cell is tightly regulated. The damaging effect of copper is seen in several hereditary forms of copper toxicity in humans and animals. At present, Wilson's disease is the best‐described and best‐studied copper‐storage disorder in humans; it is caused by mutations in theATP7Bgene. In dogs, a mutation in theCOMMD1gene has been found to be associated with copper toxicosis. Using a liver‐specificCommd1knockout mouse, the biological role of Commd1 in copper homeostasis has been confirmed. Yet, the exact mechanism by which COMMD1 regulates copper homeostasis is still unknown. Here, we give an overview of the current knowledge and perspectives on the molecular function of COMMD1 in copper homeostasis.Keywords
