The prion protein unstructured N‐terminal region is a broad‐spectrum molecular sensor with diverse and contrasting potential functions
Bibliographic record
Abstract
The physiological function of the prion protein (PrP(C) ) and its conversion into its infectious form (PrP(Sc) ) are central issues to understanding the pathogenesis of prion diseases. The N-terminal moiety of PrP(C) (NH(2) -PrP(C) ) is an unstructured region with the characteristic of interacting with a broad range of partners. These interactions endow PrP(C) with multifunctional and sometimes contrasting capabilities, including neuroprotection and neurotoxicity. Recently, binding of β-sheet rich conformers to NH(2) -PrP(C) demonstrated a probable neurotoxic function for PrP(C) in Alzheimer's disease. NH(2) -PrP(C) also enhances the propagation of prions in vivo and is the target of the most potent antiprion compounds. Another level of complexity is provided by endoproteolysis and release of most of NH(2) -PrP(C) into the extracellular space. Further studies will be necessary to understand how NH(2) -PrP(C) regulates the physiological function of PrP(C) and how it is involved in the corruption of its normal function in diseases.

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.
