ARF (ADP Ribosylation Factor)

ARF (ADP Ribosylation Factor) is a small protein involved in cellular processes, primarily regulating the movement of materials within the cell. It acts as a molecular switch, toggling between active and inactive states to control the formation of membrane structures like vesicles, which transport molecules. ARF is essential for processes such as vesicle formation, lipid modification, and maintaining cell shape. By coordinating these activities, ARF helps cells communicate, grow, and respond to their environment efficiently.
