Intraflagellar transport (IFT) is the bi-directional movement of particles along the length of cilia/flagella (terms used interchangeably here)(reviewed in Rosenbaum and Witman, 2002; Baldari and Rosenbaum, 2010). This movement was first observed in Chlamydomonas reinhardtii by differential interference contrast microscopy (DIC)(Kozminski et al., 1993). Later, fluorescence microscopy (especially total internal reflection fluorescence [TIRF] microscopy) was widely used to observe the movement of individual proteins during IFT (Engel et al., 2009). Shortly after the discovery of IFT, the motor protein that powers the movement from the base of the flagellum to the tip (anterograde IFT) was found to be heterotrimeric kinesin 2 (composed of FLA10, FLA8, and FLA3 in Chlamydomonas; KIF3A, KIF3B, and KAP in mammals)(Walther et al., 1994; Kozminski et al., 1995; Morris and Scholey, 1997; Cole et al., 1998; Nonaka et al., 1998). Over the years, additional kinesins were found to be involved in anterograde IFT in Caenorhabditis elegans and mammals. It appears that the heterotrimeric kinesin-2 motor is part of the core IFT machinery that functions wherever IFT occurs, whereas accessory kinesins function in a cell-specific manner to generate diversity in ciliary shape and function (Verhey et al., 2011). By taking advantage of the Chlamydomonas fla10 temperature-sensitive mutant, two groups initially isolated at least 15 proteins that compose the particles moving during IFT (Piperno and Mead, 1997; Cole, et al., 1998). To date, at least 22 IFT-particle proteins have been identified (Ou et al., 2005; Taschner et al., 2012; Ishikawa et al., 2014); these proteins form two different complexes, termed IFT-A and IFT-B. The motor protein that powers the movement of the particles from the tip of the flagellum to the base (retrograde IFT) is called cytoplasmic dynein 1b in Chlamydomonas and cytoplasmic dynein 2 in vertebrates. Here, for simplicity, we collectively refer to the dyneins that power retrograde IFT as IFT dyneins.© 2015 Published by Elsevier Inc.* To whom correspondence should be addressed: George.
