RP2 is an ARL3 GAP that is localized to the cilium and plays a role in trafficking proteins from the Golgi to the ciliary membrane (Veltel et al, 2008a; Hurd et al, 2011; Evans et al, 2010; Wright et al, 2011). RP2 forms a ternary complex with UNC119B and ARL3, activating the ARL3 GTPase activity and promoting the release of UNC119B (Veltel et al, 2008b; Wright et al, 2011; Kuhnel et al, 2006; reviewed in Schwarz et al, 2012; Li et al, 2012)
