Jun Protein is a type of protein that plays a crucial role in regulating gene expression. It is part of the AP-1 transcription factor complex, which is involved in various cellular processes, including cell growth, differentiation, and response to stress. This protein is encoded by the JUN gene and is essential for normal cellular function. Abnormal levels of Jun Protein can be linked to various diseases, including cancer, as it can influence cell proliferation and survival. Understanding its function helps researchers develop targeted therapies for related health conditions.
