ceruloplasmins

Ceruloplasmin is a copper-transporting protein found in the blood plasma of humans and other mammals. It is primarily synthesized by the liver and plays a crucial role in the transport of copper from the liver to various tissues, where it is stored in specific organs such as the brain, liver, and bone. Ceruloplasmin is also involved in the regulation of iron metabolism by facilitating the transfer of iron from ferritin to transferrin, which is then distributed to other tissues.

The protein is a homotetramer, consisting of four identical subunits, each containing a single copper atom. The copper atoms are coordinated in a type 1 copper site, which is essential for the protein's function. Ceruloplasmin has been shown to have antioxidant properties, as it can scavenge reactive oxygen species and protect cells from oxidative damage. Additionally, it has been implicated in the pathogenesis of various diseases, including Wilson's disease, a genetic disorder characterized by the accumulation of copper in the body.

Ceruloplasmin levels in the blood can be used as a diagnostic tool for certain conditions. For example, low ceruloplasmin levels are often associated with Wilson's disease, while high levels may be indicative of other conditions such as liver disease or inflammatory disorders. However, it is important to note that ceruloplasmin levels can be influenced by various factors, including age, sex, and certain medications, and should be interpreted with caution.

In summary, ceruloplasmin is a vital copper-transporting protein that plays a crucial role in copper homeostasis and iron metabolism. Its levels in the blood can be used as a diagnostic tool for certain conditions, but should be interpreted with caution. Further research is needed to fully understand the role of ceruloplasmin in health and disease.
