Structural characterization of the<i>Saccharomyces cerevisiae</i>autophagy regulatory complex Atg17-Atg31-Atg29
Bibliographic record
Abstract
Atg17, in complex with Atg29 and Atg31, constitutes a key module of the Atg1 kinase signaling complex and functions as an important organizer of the phagophore assembly site in the yeast Saccharomyces cerevisiae. We have determined the three-dimensional reconstruction of the full S. cerevisiae Atg17-Atg31-Atg29 complex by single-particle electron microscopy. Our structure shows that Atg17-Atg31-Atg29 is dimeric and adopts a relatively rigid and extended "S-shape" architecture with an end-to-end distance of approximately 345 Å. Subunit mapping analysis indicated that Atg17 mediates dimerization and generates a central rod-like scaffold, while Atg31 and Atg29 form two globular domains that are tethered to the concave sides of the scaffold at the terminal regions. Finally, our observation that Atg17 adopts multiple conformations in the absence of Atg31 and Atg29 suggests that the two smaller components play key roles in defining and maintaining the distinct curvature of the ternary complex.

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.
