The BBS1 component of the BBSome complex binds RAB3IP, a GEF for the small GTPase RAB8A. 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; reviewed in Zerial and McBride, 2001; Ishikawa et al, 2011; Hsiao et al, 2012; Sung and Leroux, 2013).
