Abstract

Primary cilia are antenna‐like sensory organelles that regulate a substantial number of cellular signalling pathways in vertebrates, both during embryonic development as well as in adulthood, and mutations in genes coding for ciliary proteins are causative of an expanding group of pleiotropic diseases known as ciliopathies. Cilia consist of a microtubule‐based axoneme core, which is subtended by a basal body and covered by a bilayer lipid membrane of unique protein and lipid composition. Cilia are dynamic organelles, and the ability of cells to regulate ciliary protein and lipid content in response to specific cellular and environmental cues is crucial for balancing ciliary signalling output. Here we discuss mechanisms involved in regulation of ciliary membrane protein trafficking and signalling, with main focus on kinesin‐2 and kinesin‐3 family members.

  • Many studies in different organisms confirmed a universal requirement for heterotrimeric kinesin-2 and cytoplasmic dynein 2 in IFT, but some organisms also use accessory kinesins to regulate aspects of ciliary assembly or function.

    “A large number of studies in different organisms subsequently confirmed a universal requirement for these motors in IFT, but also demonstrated that some organisms additionally use ‘accessory’ kinesins to regulate certain aspects of ciliary assembly or function 23, 39.”

    From Cellular signalling by primary cilia in development, organ function and disease (2019) · cites this paper as [23]

    The “Intraflagellar transport” section (page not available) describes kinesin-2 and dynein 2 as IFT motors, but says mutations in their subunits usually cause severe ciliary defects in most organisms studied—not that their requirement is universal. The “Role of kinesin-2 motors in axoneme extension” section (page not available) describes additional kinesin-2 motors with overlapping or partially redundant roles in some organisms, supporting the accessory-motor part of the claim.

  • The mechanisms that control the balanced output of ciliary signaling described in this Review might also apply to other pathways such as Hippo and Notch signaling pathways or those regulated by receptors of extracellular matrix molecules, which also have been linked to primary cilia in various cell types and tissues.

    “The mechanisms that control the balanced output of ciliary signalling described in this Review might also apply to other pathways such as Hippo and Notch signalling pathways or those regulated by receptors of extracellular matrix molecules, which also have been linked to primary cilia in various cell types and tissues 23, 291, 292.”

    From Cellular signalling by primary cilia in development, organ function and disease (2019) · cites this paper as [23]

    The Introduction links Notch and Hippo signalling to primary cilia, and the TGF-β/BMP signalling section describes ciliary control of balanced signalling output. The paper does not substantiate the additional claim that pathways regulated by receptors of extracellular-matrix molecules are linked to primary cilia in various cell types and tissues. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Vesicular transport pathways deliver specific receptors or signalling molecules from the Golgi or recycling endosome to the ciliary base, where vesicles are exocytosed.

    “These include vesicular transport pathways that target specific receptors or signalling molecules from the Golgi or recycling endosome to the ciliary base where vesicles are exocytosed 22, 23,”

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.
