The RAB8 guanine nucleotide exchange factor RAB3IP/RABIN8 is recruited to vesicles through interaction with membrane-tethered RAB11:GTP (Westlake et al, 2011; Knodler et al, 2010). Recruitment of RAB3IP may also depend on the TRAPPCII complex, a multiprotein complex with roles in vesicular trafficking (Westlake et al, 2011; reviewed in Sacher et al, 2008). RAB3IP is required for RAB8A to localize to the cilium, and depletion of RAB3IP compromises cilia formation (Nachury et al, 2007; Loktev et al, 2008). GTP-bound RAB8A may promote ciliogenesis by promoting the traffic of post-Golgi vesicles to the base of the cilium (Nachury et al, 2007; Westlake et al, 2011; Feng et al, 2012; reviewed in Reiter et al, 2012)
