RhoG is a member of the Rho family of GTPases, which are proteins that play a crucial role in regulating various cellular processes. It is involved in controlling the actin cytoskeleton, influencing cell shape, movement, and adhesion. RhoG is activated by signaling molecules and can switch between an active and inactive state, allowing it to respond to different cellular signals. In addition to its role in cell movement, RhoG is also implicated in processes such as endocytosis and exocytosis, which are essential for nutrient uptake and secretion of substances from cells. Its activity is important for normal cellular function and can impact various biological processes, including immune responses and tissue development.
