Characterization of the promoter activity of a poxvirus conserved element
Bibliographic record
Abstract
The conserved sequence element (CSE) is a highly conserved 42-bp poxvirus sequence that can function as a poxvirus promoter element. The CSE is composed of 2 repeats, each containing the highly conserved late poxvirus promoter sequence TAAAT. To define the location of the nucleotides critical for promoter function, polymerase chain reaction was carried out using primers that inserted modified versions of the CSE upstream of the green fluorescent protein (GFP), and the constructs were transiently transfected into cells by using GFP levels as a measure of promoter function. The results of this analysis revealed that the second TAAAT sequence, but not the first TAAAT sequence, is critical for promoter function of the CSE. Furthermore, deletion of half of the intervening sequence, i.e., from 10 to 5 nt, increases the promoter strength of the CSE as compared with the wild-type CSE. These results indicate the potential of this novel poxvirus promoter for driving high levels of gene expression.

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.
