Caspase‐3‐mediated cleavage of Akt: Involvement of non‐consensus sites and influence of phosphorylation
Bibliographic record
Abstract
Here, we show for the first time that Akt1 is cleaved in vitro at the caspase-3 consensus site DQDD(456) downward arrow SM. Our data suggest QEEE(116) downward arrow E(117) downward arrow MD, EEMD(119) downward arrow, TPPD(453) downward arrow QD and DAKE(398) downward arrow IM as novel non-consensus caspase-3 cleavage sites. More importantly, we demonstrate that phosphorylation of Akt1 modulates its cleavage in a site-specific manner: Resistance to cleavage at site DAKE(398) (within the kinase domain) in response to phosphorylation suggests a possible mechanism by which the anti-apoptotic role of Akt1 is regulated. Our result is important in biological models which rely on Akt1 for cell survival.

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.
