RAS GTPase
RAS GTPase is a small protein that acts as a molecular switch inside cells, helping regulate processes like cell growth, division, and survival. It cycles between an active form (bound to GTP) and an inactive form (bound to GDP). When activated, RAS triggers pathways that promote cell functions; when inactivated, these pathways are turned off. Proper RAS function is essential for normal cell behavior, but mutations can cause RAS to stay active, leading to uncontrolled cell growth and cancer. Thus, RAS GTPase plays a critical role in cell signaling and health.
