Inhibition of Yap2 activity by MAPKAP kinase Rck1 affects yeast tolerance to cadmium
Bibliographic record
Abstract
Yap2 is a cadmium responsive transcription factor that interacts with MAPK-activated protein (MAPKAP) kinase Rck1. We show that Rck1 deletion confers protection against cadmium toxicity and that the mechanism underlying this observation relies on Yap2. Rck1 removal from the yeast genome potentiates Yap2 activity by increasing protein half-life and delaying its nuclear export. As a consequence, several Yap2 antioxidant targets are over-activated by a mechanism that also requires Yap1. Several genes of the cell wall integrity (CWI) pathway are upregulated under cadmium stress in a Yap2 dependent way. We showed that deletion of CWI genes renders yeast cells more sensitive to cadmium. These findings led us to suggest that in response to cadmium stress Yap2 may serve a dual purpose: oxidative stress attenuation and cell wall maintenance.

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.
