Coordination of Rab8 and Rab11 in primary ciliogenesis
Bibliographic record
Abstract
Primary cilia are microtubule-based membrane projections located at the surface of many cells. Defects in primary cilia formation have been implicated in a number of genetic disorders, such as Bardet-Biedl Syndrome and Polycystic Kidney Disease. Recent studies have demonstrated that polarized vesicular transport involving Rab8 and its guanine nucleotide-exchange factor Rabin8 is essential for primary ciliogenesis. Here we report that Rabin8 is a direct downstream effector of Rab11, which functions in membrane trafficking from the trans-Golgi network and recycling endosomes. Rab11, in its GTP-bound form, interacts with Rabin8 and kinetically stimulates the guanine nucleotide-exchange activity of Rabin8 toward Rab8. Rab11 is enriched at the base of the primary cilia and inhibition of Rab11 function by a dominant-negative mutant or RNA interference blocks primary ciliogenesis. Our results suggest that Rab GTPases coordinate with each other in the regulation of vesicular trafficking during primary ciliogenesis.

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.
