Generation of Recombinant Rotavirus Expressing NSP3-UnaG Fusion Protein by a Simplified Reverse Genetics System
Bibliographic record
Abstract
Previous studies generated recombinant rotaviruses that express FPs by inserting reporter genes into the NSP1 ORF of genome segment 5. Unfortunately, NSP1 is expressed at low levels in infected cells, making viruses expressing FP-fused NSP1 less than ideal probes of rotavirus biology. Moreover, FPs were inserted into segment 5 in such a way as to compromise NSP1, an interferon antagonist affecting viral growth and pathogenesis. We have identified an alternative approach for generating rotaviruses expressing FPs, one relying on fusing the reporter gene to the NSP3 ORF of genome segment 7. This was accomplished without interrupting any of the viral ORFs, yielding recombinant viruses that likely express the complete set of functional viral proteins. Given that NSP3 is made at moderate levels in infected cells, rotaviruses encoding NSP3-based FPs should be more sensitive probes of viral infection than rotaviruses encoding NSP1-based FPs.

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.
