TBC1D10A (EPI64), a RabGAP protein with a Tre-2/Bub2/Cdc16 (TBC) domain, is an effector of ARF6 and regulates ARF6-dependent membrane trafficking (Hanono et al. 2006). The TBC domain of EPI64 binds to ARF6 and stabilizes ARF6:GTP levels in a manner that is independent of its GAP activity. This interaction keeps ARF6 in an active state either by locking ARF6:GTP in an active state or may sterically hinders ARF6 from associating with its GAP, delaying the hydrolysis of bound GTP to GDP (Hokanson & Bretscher 2011).
