The role of Atg29 phosphorylation in PAS assembly
Bibliographic record
Abstract
Macroautophagy (hereafter autophagy) initiates at the phagophore assembly site (PAS), where most of the AuTophaGy-related (Atg) proteins are at least transiently localized. As the first protein complex targeted to the PAS, the Atg17-Atg31-Atg29 complex serves as the scaffold for other Atg proteins and plays a critical role for the organization of the PAS, and in autophagy initiation. We recently showed that this complex is constitutively formed and activated by the phosphorylation of Atg29 when autophagy is induced. Phosphorylation of Atg29 is required for its interaction with Atg11, another scaffold protein, and its function for promoting the proper assembly of the PAS. Single-particle electron microscopy analysis of the Atg17-Atg31-Atg29 complex reveals an elongated structure with Atg29 located at the opposing ends. This structural arrangement allows Atg29 to interact with Atg11, and is critical in the organization of the intact Atg1 complex.

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; both teacher heads agree on what is shown here.
