PI3K (Phosphoinositide 3-kinase)

PI3K (Phosphoinositide 3-kinase) is an enzyme involved in cell signaling, helping cells grow, divide, and survive. When activated by signals like growth factors, PI3K produces molecules that trigger pathways promoting these processes. It plays a crucial role in normal cell function but can contribute to cancer when it becomes overactive, leading to uncontrolled cell growth. Understanding PI3K is important for developing targeted therapies in diseases such as cancer, aiming to modulate its activity to restore normal cell behavior.
