IFT particles were first characterized in Chlamydomonas reinhardtii, where they were observed by differential interference contrast microscopy as electron-dense granules that move along doublet microtubules of the ciliary axoneme (Kozminski et al, 1993; Kozminski et al, 1995; reviewed in Pedersen et al, 2008). More recent ultrastructural analysis of Chlamydomonas flagella confirms the presence of two distinct types of IFT trains, a longer, less electron-opaque anterograde train and shorter, more opaque retrograde trains. Both the anterograde and retrograde trains are associated with the outer microtubule doublets and with the inner surface of the flagellar membrane (Pigino et al, 2009). Isolation and characterization of IFT particles revealed that they consist of 2 biochemically distinct subcomplexes, IFT A and IFT B that are widely conserved in ciliated organisms (Piperno et al, 1997; Cole et al, 1998; reviewed in Sung and Leroux, 2013). Anterograde traffic is driven by kinesin-2 type motors in an ATP-dependent manner. Evidence from C. elegans suggests distinct and sequential roles for the canonical heterotrimeric kinesin-2 motor and the alternate homodimeric kinesin-2, OSM-3 (homologue of human KIF17) in mediating anterograde transport, but this has not been demonstrated in human cells where the canonical kinesin-2 motor predominates (Evans et al, 2006; Snow et al, 2004; Ou et al, 2005). Human KIF17 appears to be required in some cell types for cilia formation, and plays a role in the import of some ciliary cargo (Jenkins et al, 2006; Insinna et al, 2008; Insinna et al, 2009; Dishinger et al, 2010; reviewed in Verhey et al, 2011). Assembly of the anterograde IFT trains at the base of the cilium may be facilitated by the BBSome complex, which has also been shown to display IFT-like movement along the axoneme; however, the BBSome is highly sub-stoichiometric with respect to the IFT complex, so this notion requires more substantiation (Ou et al, 2005; Wei et al, 2012; Blacque et al, 2004; Nachury et al, 2007; Lechtreck et al, 2009; reviewed in Sung and Leroux, 2013). Studies in C. elegans also suggest a role for ARL13B and ARL3 in regulating the stability of the anterograde IFT train (Li et al, 2010).
