The Intraflagellar Transport Machinery

Open access

Abstract

Eukaryotic cilia and flagella are evolutionarily conserved organelles that protrude from the cell surface. The unique location and properties of cilia allow them to function in vital processes such as motility and signaling. Ciliary assembly and maintenance rely on intraflagellar transport (IFT), the bidirectional movement of a multicomponent transport system between the ciliary base and tip. Since its initial discovery more than two decades ago, considerable effort has been invested in dissecting the molecular mechanisms of IFT in a variety of model organisms. Importantly, IFT was shown to be essential for mammalian development, and defects in this process cause a number of human pathologies known as ciliopathies. Here, we review current knowledge of IFT with a particular emphasis on the IFT machinery and specific mechanisms of ciliary cargo recognition and transport.

  • Subsequent work in protists and metazoans, including Tetrahymena, Trypanosoma, C. elegans, sea urchin, zebrafish, mouse and human, substantiated the evolutionary conservation of IFT and provided insight into its molecular workings and physiological roles.

    “Subsequent work in a range of additional organisms, including protists such as Tetrahymena thermophila and Trypanosoma brucei and metazoans like C. elegans, sea urchin, zebrafish, mouse, and human, have substantiated this view, and provided remarkable insight into the molecular workings and physiological roles of IFT 25, 30, 31, 46.”

    The paper’s discovery and IFT-A sections describe IFT findings in Tetrahymena, Trypanosoma, C. elegans, zebrafish and mammals, including molecular functions and disease relevance (page unavailable in our copy). Its only sea-urchin mention is a reference to a kinesin purified from sea-urchin eggs; it does not describe sea-urchin work substantiating IFT conservation or clarifying IFT’s roles.

  • The three-dimensional structures of many IFT-B polypeptides have been solved, and progress has been made in understanding the arrangement and interactions of individual IFT polypeptides within the IFT-A and IFT-B sub-complexes.

  • The intraflagellar transport system moves along axonemal microtubules to carry specific ciliary cargo proteins into or out of the organelle.

    “and the intraflagellar transport (IFT) system that zips up and down axonemal microtubules to mediate the transport of specific ciliary cargo proteins into or out of the organelle 24, 25 (Figure 1).”
  • These IFT polypeptides can be subdivided into IFT-A, IFT-B1 and IFT-B2 sub-complexes containing 6, 10 and 6 different IFT particle proteins, respectively.

    “We now know these polypeptides can be subdivided into IFT-A, IFT-B1 and IFT-B2 sub-complexes that contain 6, 10 and 6 different IFT particle proteins, respectively 25, 30, 31, 46, 47.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
