ARF proteins

ARF proteins, or ADP-ribosylation factors, are a group of proteins involved in cellular processes, particularly in the transport of molecules within cells. They play a crucial role in regulating vesicle formation, which is how cells move and store substances. By helping to shape membranes and recruit other proteins, ARF proteins ensure that cells function properly, contributing to processes like communication, nutrient uptake, and waste removal. Their correct functioning is essential for maintaining overall cell health and may be implicated in various diseases when they malfunction.
