PTEN: A Novel Anti-oncogenic Function Independent of Phosphatase Activity
Bibliographic record
Abstract
The PTEN gene is an important tumor suppressor mutated in a number of cancers. To date, its growth regulatory properties have been intimately linked to its ability to act as a protein and phosphoinositol phosphatase. Inactivation of the enzymatic activity of PTEN is primarily due to direct mutation of its amino-terminal catalytic domain but approximately 20% of mutations are in the carboxy-terminus, which regulates membrane localization, protein stability, cellular migration and p53 function. We identified a novel protein that interacts with this domain, the v-jun transcriptional target, MSP58. Binding of MSP58 to PTEN results in the suppression of MSP58-mediated transformation. However, this PTEN effect does not require its catalytic activity, suggesting additional mechanisms of PTEN action.

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.
