About the Jun protein, the most abundant protein in your cells. The Jun protein is also called the Fos protein. It plays a role in regulating gene transcription.
What does that mean? It means that the Jun protein plays a very important role in the regulation of cell growth and death. It acts as a tumor suppressor and is considered to be a negative regulator of cellular proliferation.
The Jun protein is made of two different proteins. One is the Jun proto-oncogene protein (also called c-Jun). It is known to play a role in regulating gene transcription. Another one is the Jun dimerization protein 2 (also known as JDP- 2 or AF13). It helps regulate cellular Conzort proliferation and death and regulates the activity of the Jun proto-oncogene protein.
The Jun protein also works with other proteins to control cell division and to make sure that your DNA is replicated accurately. It does this by forming a complex called the AP- 1 transcription factor that works in the nucleus of your cell.
The Jun protein is very important in cancer. Cancer cells do not have as much Jun protein as normal cells do. So the Jun protein is able to regulate cellular growth. Because of its function in regulating gene transcription, the Jun protein is thought to be a tumor suppressor.
