Conserved regions of bovine adenovirus-3 pVIII contain functional domains involved in nuclear localization and packaging in mature infectious virions
Bibliographic record
Abstract
Adenoviruses are non-enveloped DNA viruses that replicate in the nucleus of infected cells. One of the core proteins, named pVIII, is a minor capsid protein connecting the core with the inner surface of the capsid. Here, we report the characterization of minor capsid protein pVIII encoded by the L6 region of bovine adenovirus (BAdV)-3. Anti-pVIII serum detected a 24 kDa protein at 12-48 h post-infection and an additional 8 kDa protein at 24-48 h post-infection. While the 24 kDa protein was detected in empty capsids, only the C-terminal-cleaved 8 kDa protein was detected in the mature virion, suggesting that amino acids147-216 of the conserved C-terminus of BAdV-3 pVIII are incorporated in mature virions. Detection of hexon protein associated with both precursor (24 kDa) and cleaved (8 kDa) forms of pVIII suggest that the C-terminus of pVIII interacts with the hexon. The pVIII protein predominantly localizes to the nucleus of BAdV-3-infected cells utilizing the classical importin α/β dependent nuclear import pathway. Analysis of mutant pVIII demonstrated that amino acids 52-72 of the conserved N-terminus bind to importin α-3 with high affinity and are required for the nuclear localization.

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.
