ADP-ribosylation factor 5, also known as ARF5, is a small guanine nucleotide-binding protein that enhances the enzymatic activities of cholera toxin. ARF-dependent regulatory mechanisms include the coordination of spectrin interactions with golgi membranes and the association of actin to the golgi via rho family-dependent G-protein localization and WASP/Arp2/3 complexes. ARF5 is involved in vesicular transport and functioning via phospholipase D activation. Purified by using conventional chromatography techniques. Source: Recombinant corresponding to aa1-180 of human ARF5, fused to His-tag at N-terminal, expressed in E.coli.
