Pho85, a multifunctional cyclin‐dependent protein kinase in budding yeast
Bibliographic record
Abstract
Pho85 is a multifunctional cyclin-dependent kinase (Cdk) in Saccharomyces cerevisiae that has emerged as an important model for the role of Cdks in both cell cycle control and other processes. Pho85 is targeted to its substrates by 10 different cyclins or Pcls. Three of these Pcls have specific roles in G1 phase of the cell cycle, both in regulating G1-specific gene expression and in controlling polarized growth. Many known substrates of the G1 forms of Pho85 are also phosphorylated by the homologous Cdk Cln-Cdc28, suggesting parallel or overlapping roles. Most of the remaining Pcls function in signalling: Pho85 is generally active when environmental conditions are satisfactory, phosphorylating proteins involved in transcription and other regulatory events to keep the stress response and inappropriate activities turned off. Recently, genetic screens for synthetic lethality and synthetic dosage lethality, and proteomic screens for in vitro Pho85 substrates, have revealed more details about how Pho85 functions to regulate a variety of cellular processes.

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.
