PEX14 powers OPTN (optineurin) to drive peroxisome turnover
Bibliographic record
Abstract
Cells maintain organelle integrity and metabolic balance through tightly coordinated quality control systems. Autophagy plays a central role by recycling damaged and unnecessary cellular components, with selective pathways providing specificity through dedicated receptors. Although OPTN is well-established as a receptor for mitophagy, aggrephagy, and xenophagy, its role in pexophagy, the selective autophagic degradation of peroxisomes, has only recently been recognized. Our recent work identifies the peroxisomal membrane protein PEX14 as a critical docking platform for OPTN, enabling recruitment of autophagic machinery and initiation of pexophagy. How PEX14 engages OPTN, what triggers this interaction, and how it drives the autophagic engulfment of peroxisomes remain unclear. In this punctum, we contextualize our findings and highlight unresolved questions that must be addressed to understand the physiological and pathological relevance of this process.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
