Isolation and Characterization of a Silkworm cDNA Encoding a Protein Homologous to the 14kDa Protein of Bovine Ubiquinol-cytochrome C Reductase
Bibliographic record
Abstract
In this study, we characterized the small subunit of ubiquinol-cytochrome C reductase (Bmuccr) of the silkwormBombyx mori, a model insect of Lepidopteron species. The Bmuccr gene covers a 1.4 kb genome region and contains 3exons. The ORF contained 354bp and encoded 117 amino acid residues, which shares 69% overall amino acid sequenceidentities with the subunit VII of ubiquinol-cytochrome C reductase from bovine. Phylogenetic tree showed Bmuccr hadhigh homology with T. castaneum homologous. The multiple sequence alignment of 16 subunit VII homologues showsthat Bmuccr is very hydrophilic, has a characteristic charge distribution, and has a high helical content. Expressionanalysis indicated that Bmuccr was highly expressed in larva stage and was down-regulated in embryos stage and adultstage of silkworm. The tissue-specific expression indicated Bmuccr had high-expression level in tissues that consumeoxygen. The analysis of domain structure of this protein suggested that it might be involved in correct assembly of thecytochrome bcl complex. Definition of the homologous of bovine subunit VII of ubiquinol-cytochrome C reductaseshould facilitate further analysis of structure/function relationships of silkworm cytochrome bcl complex.

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.
