The irreversible binding of amyloid peptide substrates to insulin-degrading enzyme
Bibliographic record
Abstract
Insulin-degrading enzyme (IDE) is a conserved Zn(2+)metalloendopeptidase involved in insulin degradation and in the maintenance of brain steady-state levels of amyloid beta peptide (Abeta) of Alzheimer's disease (AD). Our recent demonstration that IDE and Abeta are capable of forming a stoichiometric and extremely stable complex raises several intriguing possibilities regarding the role of this unique protein-peptide interaction in physiological and pathological conditions. These include a protective cellular function of IDE as a "dead-end chaperone" alternative to its proteolytic activity and the potential impact of the irreversible binding of Abeta to IDE upon its role as a varicella zoster virus receptor. In a pathological context, the implications for insulin signaling and its relationship to AD pathogenesis are discussed. Moreover, our findings warrant further research regarding a possible general and novel interaction between amyloidogenic peptides and other Zn(2+)metallopeptidases with an IDE-like fold and a substrate conformation-dependent recognition mechanism.

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.
