ARFIP2, arfaptin 2, ADP-ribosylation factor interacting protein 2, Partner of RAC1, POR1, ARFP2_HUMAN .
ARFIP2 is a ubiquitously expressed protein implicated in mediating cross talk between RAC and ARF small GTPases. It has been shown that ARFIP2 binds specifically to GTP-bound ARF1 and ARF6, but binds to Rac-GTP and Rac-GDP with similar affinities. The X-
