ADP-ribosylation factor (ARF)-related protein 1 (ARFRP1) is a small GTPase with significant similarity to the ARF family. However, little is known about the function of ARFRPI in mammalian cells, although knockout mice of its gene are embryonic lethal. In the present study, we demonstrate that ARFRP1 is associated mainly with the trans-Golgi compartment and the trans-Golgi network (TGN) and is an essential regulatory factor for targeting of Arl1 and GRIP domain-containing proteins, golgin-97 and golgin-245, onto Golgi membranes. Furthermore, we show that, in concert with Arl1 and GRIP proteins, ARFRPI is implicated in the Golgi -to-plasma membrane transport of the vesicular stomatitis virus G protein as well as in the retrograde transport of TGN3S and Shiga toxin from endosomes to the TGN.
