Rab1b-GBF1-ARF1 Secretory Pathway Axis Is Required for Birnavirus Replication
Bibliographic record
Abstract
Birnaviruses are unconventional members of the dsRNA viruses, with the lack of a transcriptionally active core being the main differential feature. This structural trait, among others that resemble those of the plus single-stranded (+ssRNA) viruses features, suggests that birnaviruses might follow a different replication program from that conducted by prototypical dsRNA members and the hypothesis that birnaviruses could be evolutionary links between +ssRNA and dsRNA viruses has been argued. Here, we present original data showing that IBDV-induced GC reorganization and the cross talk between IBDV and the Rab1b-GBF1-ARF1 mediate the intracellular trafficking pathway. The replication of several +ssRNA viruses depends on the cellular protein GBF1, but its role in the replication process is not clear. Thus, our findings make a substantial contribution to the field of birnavirus-host cell interactions and provide further evidence supporting the proposed evolutionary connection role of birnaviruses, an aspect which we consider especially relevant for researchers working in the virology field.

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.
