ADP-ribosylation factor

ADP-ribosylation factor (ARF) is a small protein that plays a key role in cell function by helping transport materials within cells. It acts like a switch, turning on and off processes involved in forming vesicles—tiny bubbles that carry proteins and other molecules to different parts of the cell. ARF ensures these vesicles form correctly and reach their destinations, maintaining the cell’s organization and communication. This process is essential for cell growth, secretion, and communication, making ARF vital for healthy cellular activity.
