Abstract
Vts1p is the Saccharomyces cerevisiae member of the Smaug family of post-transcriptional regulators, which is a group of sequence-specific RNA-binding proteins that regulate target mRNA expression. Vts1p is known to mediate deadenylation-dependent degradation of target transcripts through the recruitment of the Ccr4p/Pop2p/Not deadenylase complex. By conducting a functional analysis of Vts1p deletion mutants, I demonstrate that two regions within Vts1p are independently capable of downregulating the expression of an mRNA reporter. I provide both genetic and biochemical evidence that suggests residues 170-523 regulate reporter expression at the level of mRNA stability and function through a mechanism that requires the Ccr4p/Pop2p/Not deadenylase, whereas residues 1-237 repress reporter expression at the level of translation and function through a novel mechanism. In addition, I map a direct interaction between the eIF4E-binding protein, Eap1p, and the Vts1p SAM domain, which suggests a model in which residues 170-523 recruit Eap1p to mediate efficient target transcript degradation.

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.
