A systematic proximity map of the centriole-cilia interface
Bibliographic record
Abstract
Eukaryotic cilia/flagella are dynamic microtubule (MT)-based organelles. The ciliary axoneme is built from a radial scaffold of 9 MT doublets, plus a central MT pair, in the case of motile cilia. The axoneme is templated by a basal body (BB)/centriole derived from the mother centriole, in the case of animal cells, which presents sub-distal and distal appendages critical for cilia formation. In vertebrates, different cilia types fulfil diverse functions, critical for embryonic development and homeostasis of adult tissues. Cilia malfunction causes ciliopathies, but despite their biomedical implications, their molecular composition and mechanisms underlying their biogenesis still remain poorly defined. In order to dissect the mechanisms involved in primary cilia assembly and disassembly we decided to focus on the mother centriole appendages and the TZ and define the interaction networks of their known components (~60 proteins) using a new mass spectrometry approach called BioID based on the proximity-dependent biotinylation of proteins by a promiscuous biotin ligase fused to the protein of interest. With this approach we have identified near neighbors and potential new interactors of ~60 known components of the centriole-cilia interface and the ciliary transition zone which have been tested for their involvement in centrosome and cilia biology using automated high-throughput/high-resolution screens and precise morphometric measurements. We identified several new regulators of ciliogenesis a subset of which we have characterized. The potential role of the most promising candidates in the potential onset of clinical features of ciliopathies will also be discussed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
