Zebrafish otud6b Negatively Regulates Antiviral Responses by Suppressing K63-Linked Ubiquitination of irf3 and irf7
Bibliographic record
Abstract
Abstract Ovarian tumor domain-containing 6B (OTUD6B) belongs to the OTU deubiquitylating enzyme family. In this study, we report that zebrafish otud6b is induced upon viral infection, and overexpression of otud6b suppresses cellular antiviral response. Disruption of otud6b in zebrafish increases the survival rate upon spring viremia of carp virus and grass carp reovirus exposure. Further assays indicate that otud6b interacts with irf3 and irf7 and diminishes traf6-mediated K63-linked polyubiquitination of irf3 and irf7. In addition, the OTU domain is required for otud6b to repress IFN-1 activation and K63-linked polyubiquitination of irf3 and irf7. Moreover, otud6b also attenuates tbk1 to bind to irf3 and irf7, resulting in the impairment of irf3 and irf7 phosphorylation. This study provides, to our knowledge, novel insights into otud6b function and sheds new lights on the regulation of irf3 and irf7 by deubiquitination in IFN-1 signaling.

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.
