Abstract

Cilia are organelles specialized for movement and signaling. To infer when during evolution signaling pathways became associated with cilia, we characterized the proteomes of cilia from sea urchins, sea anemones, and choanoflagellates. We identified 437 high-confidence ciliary candidate proteins conserved in mammals and discovered that Hedgehog and G-protein-coupled receptor pathways were linked to cilia before the origin of bilateria and transient receptor potential (TRP) channels before the origin of animals. We demonstrated that candidates not previously implicated in ciliary biology localized to cilia and further investigated ENKUR, a TRP channel-interacting protein identified in the cilia of all three organisms. ENKUR localizes to motile cilia and is required for patterning the left-right axis in vertebrates. Moreover, mutation of ENKUR causes situs inversus in humans. Thus, proteomic profiling of cilia from diverse eukaryotes defines a conserved ciliary proteome, reveals ancient connections to signaling, and uncovers a ciliary protein that underlies development and human disease.

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

  • Enkurin (CFAP106) localises near the inner junction and its disruption leads to situs inversus in humans.

    “Another protein, Enkurin (CFAP106) also localises near the inner junction and its disruption similarly leads to situs inversus in humans81, with ciliary motility defects also as a potential aetiology82.”

    From The inner junction protein CFAP20 functions in motile and non-motile cilia and is critical for vision (2022) · cites this paper as [81]

    In Results, under “Mutation of human ENKUR affects left-right axis specification” (page not supplied), the paper reports two people with situs inversus totalis whose homozygous ENKUR variant co-segregated with the condition; it says the findings suggest ENKUR mutations are a cause. It also locates ENKUR in human nasal cilia, but does not place it near the inner junction. The claim therefore adds an unsupported location and states the human causal link more firmly than the paper does. (LLM, conf=0.87)

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.
