The CP110-CEP97-CEP290 module orchestrates a centriolar satellite dependent response to proteotoxic stress
Bibliographic record
Abstract
ABSTRACT Protein degradation at the centrosome, the primary microtubule organizing centre of the cell, is critical to a myriad of cellular processes. Perturbation of the ubiquitin proteasome system causes the formation of an inclusion, or aggresome, at the centrosome. By systematic microscopy analysis, we have placed a subset of centrosomal proteins within the aggresome. Centriolar satellites, proteinaceous granules found in the vicinity of centrosomes, also became incorporated into this structure. Through high-resolution quantitative analysis, we have defined aggresome assembly at the centrosome, demonstrating a requirement for satellites in this process. Furthermore, a module consisting of CP110-CEP97-CEP290 was required to recruit aggresome components early in the pathway and senescent cells were defective in aggresome formation due to limiting amounts of CP110. Finally, satellites and the CP110-CEP97-CEP290 module were required for the aggregation of mutant huntingtin. The accumulation of protein aggregates is central to the pathology of a range of human disorders. These data thereby reveal new roles for CP110, its interactors, and centriolar satellites in controlling cellular proteostasis and the aggregation of disease relevant proteins.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
