ASAP1 is a dimeric ARF GTPase activating protein (GAP) and scaffolding protein that is recruited to the trans-Golgi network (TGN) through interactions with activated ARF4, PI(4,5)P2 and acidic phospholipids (Brown et al, 1998; Che et al, 2005; Nie et al, 2006). Once at the TGN, ASAP1 forms a tripartite complex with ARF4 and ciliary cargo, possibly by interacting with a putative C-terminal FR targeting motif present in a number of membrane proteins destined for the cilium, although this remains to be conclusively demonstrated (Corbit et al, 2005; Wang et al, 2012; reviewed in Bhogaraju et al, 2013). In addition to its role as an ARF GAP, ASAP1 also scaffolds the recruitment of a number of other proteins required for ciliary targeting, including RAB11 and the RAB11 effector FIP3 (Mazelova et al, 2009; Inoue et al, 2008; reviewed in Deretic 2013).
