ARF3, functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. This protein involved in protein trafficking, may modulate vesicle budding and uncoating within the Golgi apparatus. Source: Recombinant corresponding to aa1-181 from human ARF3, fused to His-tag at N-terminal expressed in E.coli.
