Ras protein is a small GTPase that plays a crucial role in cell signaling. It acts as a molecular switch, toggling between an active form bound to GTP and an inactive form bound to GDP. This switching regulates various cellular processes, including growth, differentiation, and survival. Mutations in Ras protein are commonly associated with several types of cancer, making it a significant focus in cancer research. Understanding how Ras functions and its role in signaling pathways can help develop targeted therapies to treat cancer more effectively.
