The roles of the human lipid-binding proteins ORP9S and ORP10S in vesicular transport
Bibliographic record
Abstract
Inactivation of the yeast oxysterol binding protein related protein (ORP) family member Kes1p allows yeast cells to survive in the absence of Sec14p, a phospholipid transfer protein required for cell viability because of the role it plays in transporting vesicles from the Golgi. We expressed human ORP9S and ORP10S in yeast lacking Sec14p and Kes1p function, and found that ORP9S completely complemented Kes1p function, whereas ORP10S possessed only a weak ability to replace Kes1p function. Purified ORP9S protein bound several phosphoinositides, whereas ORP10 bound specifically to phosphatidylinositol 3-phosphate. The combined evidence demonstrates that only a subset of human ORP proteins can function as negative regulators of Golgi-derived vesicular transport.

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.
