Protein Tyrosine Phosphatases: Emerging Regulators of Apoptosis
Bibliographic record
Abstract
Apoptosis is a precisely controlled physiological mechanism that is required for the elimination of cells during embryonic development, in response to stress and infection as well as in the maintenance of homeostasis. Since the outcome of several of these biological processes is regulated by signaling events involving tyrosine phosphorylation, members of the protein tyrosine phosphatase (PTP) gene family are expected to be of primary importance. Here, we summarize the current literature linking the activities of classical PTPs with the regulation of apoptosis. The recent discovery of caspase-cleavage mediated modulation of a member of this family, PTP-PEST, indicates that other PTPs could be modulated in a similar manner. In light of this, we present an analysis of all murine and human PTPs gene for the presence of putative caspase cleavage motifs. Additional studies linking the activity of PTPs to their own regulation during programmed cell death initiation should provide important insight into the understanding of this fundamental physiological phenomenon.

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.
