IFT–Cargo Interactions and Protein Transport in Cilia

Open access
Lechtreck, Karl F.·2015·Trends in Biochemical Sciences

Abstract

The motile and sensory functions of cilia and flagella are indispensable for human health. Cilia assembly requires a dedicated protein shuttle, intraflagellar transport (IFT), a bidirectional motility of multi-megadalton protein arrays along ciliary microtubules. IFT functions as a protein carrier delivering hundreds of distinct proteins into growing cilia. IFT-based protein import and export continue in fully grown cilia and are required for ciliary maintenance and sensing. Large ciliary building blocks might depend on IFT to move through the transition zone, which functions as a ciliary gate. Smaller, freely diffusing proteins, such as tubulin, depend on IFT to be concentrated or removed from cilia. As I discuss here, recent work provides insights into how IFT interacts with its cargoes and how the transport is regulated.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Progress has been made in understanding interactions between specific IFT particle polypeptides and specific ciliary cargo proteins or motor subunits during anterograde or retrograde IFT, as well as how IFT motor activity is regulated.

    “Likewise, progress has been made towards understanding the interactions between specific IFT particle polypeptides and specific ciliary cargo proteins or motor subunits during anterograde or retrograde IFT, as well as how IFT motor activity is regulated 24, 48–52.”

    From Cellular signalling by primary cilia in development, organ function and disease (2019) · cites this paper as [24]

    The sections on cargo binding and known IFT binding sites describe specific interactions, including IFT81/IFT74 with tubulin and IFT46 with an adaptor for outer dynein arms. The building-blocks section identifies the motors for anterograde and retrograde transport, but the paper does not substantively explain how IFT motor activity is regulated or establish the claimed interactions with specific motor subunits.

  • 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).”

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.
