GTP-binding protein that may be involved in protein trafficking; may modulate vesicle budding and uncoating within the Golgi apparatus (By similarity). Plays a role in the shedding of pathogen spores from intestinal cells (PubMed:24843160). RNAi-mediated knockdown results in disrupted clearance of intracellular pathogen N.parisii from intestinal cells. Belongs to the small GTPase superfamily. Arf family.
