Abstract
HSF-1 is a highly conserved transcription factor that plays a central role in protecting organisms from diverse cellular stresses. However, the mechanisms by which HSF-1 senses and responds to different types of stress remain incompletely understood. COPII-coated vesicles, responsible for transporting cargo from the endoplasmic reticulum to the Golgi apparatus, are essential for protein secretion and cellular homeostasis. Disruption of these vesicles impairs protein secretion and triggers severe proteotoxic stress. Here, we show that HSF-1 directly monitors COPII vesicle dysfunction through interactions with the core COPII component SEC-23, in both Caenorhabditis elegans and NIH3T3 cells. Inhibition of SEC-23 or SAR-1 disrupts COPII vesicle formation, leading to the release of HSF-1 from the COPII complex. This release induces a specific transcriptomic change to restore protein homeostasis. Our findings reveal a conserved mechanism by which HSF-1 responds to COPII vesicle dysregulation, providing new insights into the HSF-1-centered proteostasis network.

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
