Choristoneura fumiferana multiple nucleopolyhedrovirus LEF-3–P143 complex can complement DNA replication and budded virus in an AcMNPV LEF-3–P143 double knockout bacmid
Bibliographic record
Abstract
Transient replication assays using Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Choristoneura fumiferana multiple nucleopolyhedrovirus (CfMNPV) genes suggested that the interactions between P143, the viral helicase and LEF-3, a ssDNA-binding protein, may represent virus species specificity determinants. P143 and LEF-3 are essential for DNA replication in these assays and together with IE-1, the major immediate-early transcription factor, may be part of the viral replisome. In the current report, a lef-3/p143 double-knockout AcMNPV bacmid was constructed that was defective for viral DNA replication and late gene expression. When the homologous lef-3/p143 CfMNPV genes were introduced into this double-knockout bacmid, DNA replication was restored but the level of replication was lower, budded virus production was delayed, and the yields were reduced from those in an AcMNPV-rescue bacmid. These results suggest that to maximize virus replication, baculovirus replisome assembly and function requires protein-protein interactions between P143 and LEF-3, and other viral proteins.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
