Abstract
Neurodegeneration is associated with the aggregation of proteins bearing solvent-exposed hydrophobicity as a result of their misfolding and/or proteolytic cleavage. An understanding of the cellular protein quality control mechanisms which prevent protein aggregation is fundamental to understanding the etiology of neurodegeneration. By examining the metabolism of disease-linked C-terminal fragments of the TAR DNA-binding protein 43 (TDP43), we found that the Bcl-2 associated athanogene 6 (BAG6) functions as a sensor of proteolytic fragments bearing exposed hydrophobicity and prevents their intracellular aggregation. In addition, BAG6 facilitates the ubiquitylation of TDP43 fragments by recruiting the Ub-ligase, Ring finger protein 126 (RNF126). Authenticating its role in preventing aggregation, we found that TDP43 fragments form intracellular aggregates in the absence of BAG6. Finally, we found that BAG6 could interact with and solubilize additional neurodegeneration-associated proteolytic fragments. Therefore, BAG6 plays a general role in preventing intracellular aggregation associated with neurodegeneration.

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 it
