Hemagglutinin-esterase (HE) from Infectious Salmon Anemia virus (ISAv): Characteristics and attempted expression
Bibliographic record
Abstract
Infectious salmon anemia virus (ISAv) is a pathogen that mainly affects Atlantic salmon (Salmo salar), which are commonly grown in the aquaculture industry. The resulting disease, infectious salmon anemia, has caused large financial losses for this industry. ISAv is a member of the Orthomyxoviridae family, as are the influenza type A, B and C viruses, and it belongs to the genus Isavirus. ISAv has a single dual-functional surface protein that is involved in the interaction with the host cells, namely: a hemagglutinin-esterase (HE). The HE protein binds preferentially to 4-O,5-N-diacetylneuraminic acid residues that are present on the target cells, which in this case are salmon erythrocytes. As is the case for influenza, the binding of HE protein to 4-O-acetylsialosides (receptor function) triggers infection in salmon, whereas the esterase active site, which possesses the 'receptor destroying' activity hydrolyzes the 4-O-acetyl groups, aiding the release of the viral progeny to infect neighbouring cells. This thesis reports the cloning and the attempted expression of the haemagglutinin-esterase from two different ISAv strains, that is a Canadian and a Norwegian strain, using baculovirus expression systems.

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.
