Abstract
Failure to eliminate abnormal proteins in the cell is associated with numerous aggregation diseases. Misfolded proteins are normally detected by protein quality control and either refolded or eliminated. The ubiquitin-proteasome system is a major pathway that degrades these unwanted proteins. Ubiquitin ligases are central to these degradation pathways as they recognize aberrant proteins and covalently attach a polyubiquitin chain to target them to the proteasome. We discovered that the Hul5 ubiquitin ligase is a major player in a novel protein quality control pathway that targets cytosolic misfolded proteins. Hul5 is required for the maintenance of cell fitness and the increased ubiquitination of low solubility proteins after heat-shock in yeast cells. We identified several low-solubility substrates of Hul5, including the prion-like protein Pin3. It is now apparent that in the cytoplasm, misfolded proteins can be targeted by multiple degradation pathways. In this review, we discuss how the Hul5 protein quality control pathway may specifically target low solubility cytosolic proteins in the cell.

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.
